Yes... that's what I wanted to avoid. ... ...

I originally wanted to avoid calling external problems. That way,
s2ram code could be pagelocked and you would get your video back even
in case of disk problems etc.

[I thought that it would bring problems with suspend-to-both; but I
was wrong, no such problem exists.]

...and then there's a issue of how to do vbetool vbestate
save. According to docs it should be done just once, but that looks
pretty fragile to me. Perhaps we can just do it unconditionaly?
