According to the docs I have found you need to patch genkernel to
run /sbin/resume - it was a longstanding argument between two now
retired devs with the result that genkernel wont (ever) support
hibernation.  I dont know from reading the bugs if it was ever fixed now
the dev who "wouldnt" has retired, or is genkernel is still broken.

Also, I have no /sbin/resume on any of my systems (some are years old
and have been successfully running ToI for most of that time) - so how
can the initramfs actually start resumimg?

Though I have a more immediate problem - hangs on hibernation and no log
messages.
