Good point.
Declan, try this:
After making sure vbetool is installed, log into a console on vt1. Type:
vbetool post
- but don't hit return.
Suspend/resume. When everything's stabilized (the disk's stopped working),
if you don't have a screen, press Enter.
If the problem is just the blank console, this should bring it up. I've
_always_ had this problem with my Inspiron 6000 when hibernating (my
machine doesn't do "suspend") from a console (it didn't used to be a
problem if I did it from my KDE session, though it broke with some kernel
upgrade, and I added "vbetool post" permanently to the resume script).
