Not on this system, anyway.  Or, at least, it doesn't seem to; it seems to
hibernate to part of the Windows drive when you tell Windows to hibernate.
It might be that, if I repartitioned to have a special hibernation partition,
it'd do this automatically - unfortunately, I already have 4 FDISK partitions.
(Windows, weird boot diagnostics, NetBSD, and BSD/OS.)

In Windows, anyway, my system gets as far as displaying the splash screen
before realizing that it's got a saved state to restore.  Maybe this is just
a chintzy bios, or maybe it's the hibernation partition...
