It would really be interesting to go back to an earlier kernel. You 
should be able to set which kernel is booted by default in the grub.conf 
file, but I don't know where this file is on debian.

We recently tracked down a bug that appears with kernel 2.6.22 and newer 
and that may be related, so any kernel <= 2.6.21 would be a good test. 
Or alternatively, try to update your drm kernel modules :

git clone git://anongit.freedesktop.org/git/mesa/drm
cd drm
cd linux-core
make LINUXDIR=/lib/modules/`uname -r`/build DRM_MODULES=via
cp *.ko /lib/modules/`uname -r`/kernel/drivers/char/drm/
depmod -ae

This will remove the modules shipped with the kernel deb package, make 
sure to backup them _before_. Also, you'll need to make sure the old 
modules are unloaded before starting X. The easiest is probably to reboot.
