This is caused by the support for DRI on G33 missing in the intel driver
of the current libgl1-mesa-dri. It has been reported in bug #437333, so
we requested that upstream devs backport G33 support. It is fixed
upstream, support for G33 will be in the upcoming Mesa 7.0.2.

In meantime, either don't use GL applications, or disable DRI in
xorg.conf, or uninstall libgl1-mesa-dri (which is useless for you right
now anyway), or rebuild Mesa using the patches in#437333.

Cheers,
Brice
