Well, even without hibernation, one theory was about the VC switching
- apparently that was one thing that at least one reporter does end up
doing - switching from X into the virtual terminals and back.
That may have similar issues, and may be the deeper problem (do people
still do the VC switching *for* hibernation?)
Maybe.
