That's what I meant!  Heheh.  Since there's magic params in hardware and
for hardware, these cannot really be gathered into a state in a general
way.

I'm pondering the usefulness of trapping a reboot, ignoring operations
which would cripple the trapper, and capturing INS and OUTs, but that
seems utterly complicated and a little silly.  Fon pundering, though.

The only guarantee to having a stable system is (as some of you have
mentioned already) to use what the vendor gives you (and even then,
sometimes...) in a reboot, but for untrusted and utilitarian purposes,
such a "soft reboot" utility might be handy.

With fortune, a "pre-OS hibernation file" might only need to be captured
once.  I hope there aren't any timestamps, timing counters captured!
