ScottishDuck posted a guide on MacRumors: How to create a bootable USB Stick with Apple Mac OSX 10.8 Mountain Lion GM (Golden Master). The process is quite easy:
* Show Package Contents -> mount InstallESD.dmg
* "restore" BaseSystem.dmg to your USB drive
* System -> Installation -> Delete the link called "Packages" and then create a new folder with the same name
* Copy all the Packages to the USB Disk
* cp /Volumes/Mac\ OS\ X\ Install\ ESD/mach_kernel /Volumes/lionUSBinstaller/.
tonymacx86 released Multibeast 4.3 today - the bootloader that powers alternative hardware to boot up Mac OSX. It includes the upgrade 10.8 of Chimera, to also support Mac OS X 10.8 Mountain Lion. Furthermore, lots of other updates and changes were made (read about them below).
Today MultiBeast was updated to version 4.3 for Lion. We've added a new Combo OpenCL Enabler, which when combined with Chimera 1.8 will enable full QE/CI and OpenCL for all NVIDIA GeForce 4xx and 5xx graphics cards. Two more big additions are the flAked SpeedStepper for UEFI power management fixes, and maolj's Atheros ethernet driver. The latest version of MultiBeast is now available at tonymacx86.com/downloads.
Full changelog inside.
Besides running hackintosh on Intel Sandy Bridge-E, there are more good news from the front:
Chimera, the bootloader that powers standard PC hardware to boot up Mac OS X, received an update allowing it to support OS X Mountain Lion. To obtain OS X Mountain Lion you need an Apple Developer Account that'll cost you $99 per year, but of course your might already know where to find Mac OSX 10.8 Mountain Lion by yourself.
Today MacMan updated Chimera to version 1.8. For Mac OS X developers, OS X 10.8 Mountain Lion support has been added. This version will be included in the next MultiBeast release. (via tonymacx86)
Apple is selling Mac OSX on a Thumb Drive, but you can save some bucks and roll your own as simple as this:
1. Preparation: USB Stick
Insert an USB Stick that is big enough to fit the whole Mac OSX Lion installer. I can recommend the SanDisk Cruzer Blade 8GB, which you can get for less than $5.
2. Mac OSX Lion 10.7
get Mac OSX Lion from the App Store and download it.
3. Extracting the Install Data
Right click (option-click) on the just downloaded file and select "Show Package Contents". Get the file Contents/SharedSupport/InstallESD.dmg and copy it to your Desktop.
4. Disk Utility
Open "Disk Utility" and drag InstallESD.dmg from the desktop to the left sidebar. Select the attached USB from left side and click on “Partition” tab. Select "1 Partion" and from choose “Mac OS Extended (Journaled)” as partition type. Click on “Option” at the bottom, select “GUID Partition Table” and press OK -> Apply.
After formatting is done, select "Restore" and choose the USB Drive as destination and InstallESD.dmg as source. Click on "Restore" to have your Mac OSX Lion Boot drive created.
Tonymacx86 showed how to Install OS X 10.7 Lion on any Supported Intel Core 2 or Core i based PC with xMove + MultiBeast. Furthermore, there is a Mac OSX Lion v10.7.2-HOTiSO that should also boot from any PC. Don't forget that you need to buy Apple Mac OS X Lion from the App Store to legally use it.
OS X Lion is the next major release of OS X, the world’s most advanced desktop operating system. It includes over 250 new features that will transform how you interact with your Mac. Built on a rock-solid UNIX foundation, OS X is engineered to take full advantage of the technologies in every new Mac. And to deliver the most intuitive and integrated computer experience. Brought to us by HOTiSO group. Mac OS X 10.7 was first shown to the public in October 2010. The presentation was understated, especially compared to the bold rhetoric that accompanied the launches of the iPhone (”Apple reinvents the phone”) and the iPad (”a magical and revolutionary device at an unbelievable price”). Instead, Steve Jobs simply called the new operating system “a sneak peek at where we’re going with Mac OS X.”

As we already blogged some time ago, we had severe overheating issues and frequent kernel panics with our early 2011 models of the MacBook Pro Core-i7 quad. Still, after the updates there are crashes from time to time - the early 2011 models are far away from being stable machines to use for serious work.
After days of trying to figure out what is really the issue, we found that most of the times device drivers or other third party apps are mostly causing the crashes - but also CPU-intensive apps such as games sometimes bring the system down. Solution? Yes, there is one: change your system to a 32bit Kernel.
1) The bootup way (temporary solution, great for testing)
If you just want to test if changing to 32bit changes anything, you can reboot your mac and hold down the "3" and "2" keys as soon as you hit the power button. This boots up your Apple in 32bit mode temporarily. If the system
2) The Terminal Way (see the Apple Support Document for more information)
sudo systemsetup -setkernelbootarchitecture i386
if you need to change your system back to normal for any case, you can enter the following command into Terminal.app:
sudo systemsetup -setkernelbootarchitecture x86_64
Just to make it clear: your applications will still run in 64bit mode, you can make sure this is the case by hitting cmd+i on the application icon and see if "Open in 32-bit mode" is checked. See this article from simplehelp with details and images on 32-bit mode. So why should I care then, you might ask: since drivers and 3rd party apps and extensions that are loaded on startup are most of the time the issue with system freezes and hangs, changing to a 32bit kernel did the trick for us and now we have a stable 2011 MBP quad-core system.
[UPDATE] 10.6.8 seems to work with 64bit kernel much more stable than 10.6.7. Still, to be on the safe side we are using the 32bit kernel and had no freezes yet.
[Update 2012]: using Multibeast is the preferred way to install 10.7 Lion or 10.8 Mountain Lion

"lion is booting with some old xpc version" ~ Netkas
Some people are claiming to boot the recent Mac OSX 10.7 Lion with the XPC Bootloader project. More and more voices are popping up, so I am just pointing in the right direction, since "Any and all information about downloading and installing Lion, as well as any details are under Non-Disclosure Agreement from Apple.". You probably find updates on Netkas' Blog as well.
