To install und use the beta you must have a developer account and a Mac with Intel Core 2 Duo or better.
You can also install Lion 10.7 on older Macs by simply deleting a plist located here:
"/Volumes/Mac OS X Install ESD/System/Library/CoreServices/PlatformSupport.plist".
Some russian users from AppleLife.ru have successfully installed Lion on a hackintosh.
The only thing is that you have to boot Mac OS X 10.7 with an old Bootloader called "XPC".
And of course as of now you can only use Lion on Intel CPUs and without Chameleon Bootloader because it will not boot 10.7

In singleuser mode:
mount_hfs /dev/diskXsY /tmp, where diskXsY – partition that has fakesmc.kext
