I've recently been seeing this symptom as well. Same Debian release,
ATI RS880 video. Maybe 10% of the time, when returning from video
suspend, the screen contents come up for approximately a second and
then the monitor goes blank. Switching to a text VT and back fixes
the issue.
Only seems to be triggered on startup and return from power saving
mode.

I'm running i686, not x64, Radeon HD 4200.
