Hi Ben,
i've applied your patch and it seems that when i put my powerbook to
sleep ( by closing the lid ) the kernel just crashes since everytime i
come back, the machine is turned off. I had a look at the logs and i see
that i'm having a reboot almost immediateley after the lid is closed.
However i've got no trace of a kernel panic .....
my conf:

I have a usb mouse that i unplug before closing the lid.
Anything else that can be usefull ?
Thanks for your time.
