Bug Description
The driver for Intel chips dies after a suspend/hibernate and resume cycle.
This has been broken for most of edgy, then fixed itself for about 3 days and now has broken again:

Fatal server error:
lockup
After several tries at this, xorg will give up, and GDM will restart X, failing on another error.
mjg59 said something about Intel adding their own resume code to the i810 driver and this needs disabling as we already POST the video chip under Ubuntu.
