that's why I've always been so pleasantly surprised at how decent a
job the Dell CPi BIOS does at saving and restoring that state (in
APM mode, without OS help!) - I've been naively sleeping in X
as long as I've had the machine, and it always comes back with nothing
weirder than a few stray pixels attached to the X cursor, which go away
as soon as I move it over another window.  It's kind of an existence
proof. :)
