Thanks for the detailed explanation.  ISTR hearing that some of the
distros are working on similar solutions.  Now this would be a big win,
as anyone who has seen how much faster XP boots than Win2K can tell you.
And would certainly require kernel support.

Of course resuming from suspend will always be faster than booting but
for the forseeable future we will have to reboot from time to time.  And
XP's boot time currently is way, way better than ours.  FWIW, OSX still
takes forever to boot so we are not the only ones with this problem.

I wonder if XP's solution is patented.
