The breakage was introduced in xorg-server 2:1.9.99.901+git20110131.be3be758-0ubuntu6.

Seems like the vboxvideo DRI driver fails to load and then X crashes while trying to load a driver from the alternates dir.

A workaround is to just remove /usr/lib/dri/vboxvideo_dri.so

Last working version: xorg-server 2:1.9.99.901+git20110131.be3be758-0ubuntu5

The workaround is to downgrade to the later.

RAOF - looks like the mesa dri change broke vbox. Do they just need to rebuild their driver or is it something deeper?

No, my fault. The dri-alternates patch has an error on the (infrequently hit) failure path where the dri driver can be loaded, but isn't usable for AIGLX.
