If I have accel enabled system freezes during suspend, if accel is disabled
system suspends&resumes.
From a quick glance at the code I don't know what to do to disable accel
during suspend (and restore it on resume)...
viafb is not able to get GPU alive from its own, it still needs to have the
BIOS run VBIOS on resume.
Thanks,
Bruno
