Dr. Gilbert:

I would hazard a guess that you are actually using the ati driver. How do 3D applications run? Have you tried running any 3D apps? I know on Debian you have to explicitly change your xorg.conf to use the radeon driver or else it will use the ati driver instead.

On my ati machine, I'm using the radeon driver, which fixes the problem perfectly. When I switch back to the "ati" driver, it gets dog slow.
