Have you talked to the powermanagement guys btw.?  One of the major
issues with suspend-to-ram is to get the graphics card back online,
and SNAPBoot might help to fix this too.  I'm not sure a userspace
solution would work for *that* through.

Why not? Of course you won't get any output before the graphics card has been
re-initialized to a sane and usable state...

You have a application running which uses the framebuffer device, then
suspend with that app running.  You'll have to restore the state of
the device _before_ restarting all the userspace proccesses, otherwise
the app will not be very happy.  I'm not sure if the kernel can run a
userspace helper in that situation (i.e. before waking all the
processes).
