When the livecd boots it loads to the point of a scrambled image which resembles the windows wallpaper (colors all scrambled)
I have tried nomodeset but no joy any other suggestions would be welcome.
gpu runs 100% fine under windows and can load pre 3 kernel distros without issue
current fails are ubuntu 11.10, opensuse 12.1 rc2, fedora 16 all give the same result!
