Trouble installing f12 Beta

Hey All, I along with a bunch others have been having troubles related to: https://bugzilla.redhat.com/show_bug.cgi?id=528593 It's related to ATI r600 and r700 graphics cards and Intel ICH8, 9 and 10 based mobos. In an effort to test a few things I've tried to reinstall F12 using the Live Beta CD but the installer doesn't work. I've updated the live CD to the latest versions of anaconda, and I still get crashes (in the post install which is very annoying, and it doesn't get far enough to have all the boot stuff in place). Can someone suggest a 'working' method for installing f12 beta? Rodd
