Description of problem:
On system start up after hibernate the video screen displays black and white
think lines, the system is then rendered unusable and the only way out is
pressing the reset switch (ctrl-alt-del won't do!).

Version-Release number of selected component (if applicable):
Even though the core system is FC13, I use gdm 2.32 with kernel 2.6.35.11-83

How reproducible:
This happens at random (roughly about once every 5-6 times after
hibernate/startup). With earlier versions of the kernel (and gdm) this used to
happen more often - about once every 2-3 start ups (the reason I upgraded the
kernel and gdm).

Steps to Reproduce:
1. Hibernate the system
2. Start the system after hibernate is completed
3. Once the system starts up instead of the normal screen being restored I see
black and white lines and the whole system is rendered unusable. The syslog
(below) may indicate the reason for this.

Actual results:
