It sounds like video driver issue. Maybe you need to contract video driver writer.

Is the problem still there with latest 2.6 kernel?

If yes, can you make sure whether the problem is only with restore of the 
video (try connecting through network or serial after resume).

If it is only the video problem, 
- Please try the options in Documentation/power/video.txt
- Try the workaround in bug #3670
