OK, that's not a "problem".  That's normal.  usplash is intended to handle a
normal startup.  Even if usplash understood the resume script, it would
time out before completing resumption on my system.

This is fairly new behaviour for me (w/ Intel 915 onboard video) - but it's
consistent.  Frequently, but not always, I need to actually switch to vt1
and back before I can get access to the X display, and occasionally I also
need to close & reopen the lid to get my mouse cursor back (some kind of
BIOS video reset gets invoked by the lid-open event, I think).

It's almost to the point of being not worthwhile to use hibernate, as it can
take 10 minutes to hibernate and 2 to resume.
