Laura, just noticed an update today for xservers-xorg-video-intel:
Version 2:2.9.1-3ubuntu5:

  * Drop debian/patches/107_disable_dri_on_845_855.patch:
    + This attempt to work around the crashes on i845 and i855
documented in LP: #541492 and LP: #541511 simply shuffled the brokeness
around.  It hasn't helped enough, and it unconditionally disables 3D
which worked for some users before.

You might want to have a look at both of those bug reports as well:
