Sleep hasn't worked properly on my PowerBook G4 since I applied your
first pair of patches. The current behaviour seems to be that short
periods of sleep appear to work OK, but a fairly random death happens
after a longer sleep. Last time it was ohci_hcd complaining of an
uninitialised spinlock.

I'm half inclined to suspect RAM isn't being refreshed properly -- but
most of the kernel text still seems to be there and it manages to oops
and panic OK, so perhaps it's just that the dcache isn't correctly
disabled, or isn't correctly flushed when we enable it again?

I'll rebuild the Fedora kernel without any of the patches to eliminate
the possibility that it's caused by some other change.
