I didn't manage to crash X within an hour, so that's commit is looking 
good.

The kernel error message for i915 pipe state however still appears -
namely, whenever the X server is terminating, including "reasonably
proper" terminations induced with sending SIGTERM to the X process.
Could it be that the i915 module does not handle sudden shutdowns
(which however can occur at any time) of the /dev/dri/cardN file
descriptor well enough?
