My 945GM doesn't like coming back from suspend without being POST'd by
vbetool. Gets very nasty LCD timing as far as I can tell, and I get the
"bleeding to white / green" effect which makes me fear for the life of
my LCD.

Are you referring to different codepaths though Jesse? I'd have thought
many people end up testing the non-posted resume if they don't have /
use vbetool.
