Just in case though, assuming you guys have libgl1-mesa-dri 7.10-3 or
newer, does downgrading that to an older version fix the problem?

I had 7.10-4. Downgrading to libgl1-mesa-dri_7.7.1-4_amd64.deb seems to fix the crash.

I tried compiling the kernel to debug, but I am having some general problems. Apparently the current kernel in unstable is not compilable with the current binutils in unstable. And the latest downloaded from from kernel.org fails to mount the root filesystem. Grumble. I can find a solution, I just needed to lament a bit to somebody :).
