(I still have a suspicion that this commit, or firewire even, is not the
actual culprit.  But one never knows.)

The above bisection result is about the new stack = drivers/firewire/.
The old stack is drivers/ieee1394/ and I prefix all its changes with
"ieee1394:".

Of course the old stack is supposed to hibernate + restore properly too.
I personally tested only suspend + resume though, and that's quite long
ago...
