Which driver are you using? I am using the ATI proprietary driver
because I have a Radeon 9550. My understanding is that for Radeon
cards above 9200, the only option is the use the proprietary driver
from ATI.

Note that I'm only getting the following fps from glxgears:

Also, I'm using Xfree86 on Debian and would rather not change to xorg
at this stage. I've attached my XF86Config-4 file.
