   [i965] X freeze on karmic after resume from full screen application: i915_gem_retire_work_handler() / finish_task_switch()

** Description changed:

  This is a karmic issue of kernel 2.6.30-8 only (not 2.6.30-7, I tested it now)
  My system freezes after a period of inactivity, after the screen is blanked I cannot recover it.
