This breaks resume on the iBook G4 (PowerBook6,7). Apparently during or
before noirq resume the system is hanging by the same amount of time as
the system was sleeping.

The point where the time is wasted actually appears to be _after_ resume
(the elapsed time for the resume itself isn't affected).

I'm able to reproduce this problem on Toshiba Portege R500 with similar
symptoms, although that box sometimes hangs hard during resume from system
suspend with the "caps lock" LED blinking.
Reverting the patch fixes the problem 100% of the time.
Thanks,
Rafael
