This "I tried everything!!" stuff is always funny. If you had tried everything it would obviously work now and you wouldn't have to ask.
It would be a good starting point to explain what you're doing atm and what you've already tried.

Long shot: You are injecting a mismatched framebuffer (either through GE=Yes or AtiConfig=blabla). Don't do that, let the generic framebuffer do the work (=> GE=No, no AtiConfig stuff).
