For those of you using OpenSuSE 10.2/10.3 and most likely had your xorg.conf generated by SaX2...
The short of it is there's a regression in the 8.01 driver. http://ati.cchtml.com/show_bug.cgi?id=998
The good news is there's a simple work around for it. Find the Device section in your xorg.conf (Section "Device") and look for a line that starts with BusID. In quotes will be something like "1:0:0" (there will be different numbers depending on your card) Before that string of numbers, add "PCI:", to make it look like this: "PCI:1:0:0".

I was getting the same ASIC problem on the Radeon X1950Pro in my desktop with the 8.01 drivers on OpenSuSE 10.3. Commenting out the BusID line should work as well. You have Dieter Jurzitza to thank for tracking down the bug. I'm just passing on the good word after doing a Google search on the issue. I've got 3D acceleration and Compiz is working just fine.
