 I set vblank_mode=0 using a .drirc file in my home directory. This
 caused the overall slow down I was only experiencing after resuming from
 suspend to manifest itself all the time. Framerate in glxgears was no
 longer in sync with refresh rate, but it was quite poor (200 fps). In
 the past I've gotten more like 800 fps (radeon) and 1200 (catalyst on
 lenny). Also, only by moving the cursor with the touchpad, causes the
 framerate in glxgears to drop further.

gears is not a benchmark.  It's highly CPU dependant.


 Desktop experience is quite slow. I pulled mesa 7.10.1 from experimental
 to see if this would help, but it didn't. The good news is that, after
 waking from suspend graphics performance is the same.

 Also I would like to correct a statement I made on my first email.
 Restarting X does not fix the problem (when vblank_mode is NOT set to
 zero).

 $ glxinfo | grep renderer
 OpenGL renderer string: Gallium 0.4 on ATI RS480


Since you are using gallium make sure it is built with llvm support as
that is very important for asics without vertex hardware.  You can
also disable tear-free buffer swaps by adding:
Option SwapbuffersWait FALSE
to the device section of your xorg.conf.  That coupled with
vblank_mode=0 should give you maximum framerates at the expense of
tearing.

It isn't (yet).

Note also that I'm now using 2.6.38-2 kernel.
