I've had the same problem on two of my PCs.. one of which had two cards (Radeon X1950XTX and Radeon X1950 Crossfire series) and the other is only a single card (Radeon HD2600).. In both situations I had to revert to tty1 (ctrl+alt+f1) then install xorg-driver-flgrx and run "aticonfig --adapter=all --initialize", then restart gdm. This worked greatly. I even was able to use compiz and it went smoothly.
If you need any information i'll be glad to provide them.
