I'll try. My goal was not to add or change not functionality but to
make what the kernel was already doing be consistent.

It turns out the device_suspend(PMSG_FREEZE) is a major pain
sitting in the reboot path and I will be submitting a patch to
remove it from the reboot path in 2.6.13 completely.

At the very least the ide driver breaks, and the e1000 driver
is affected.

And there is of course the puzzle of why there exists simultaneously
driver shutdown() and suspend(PMSG_FREEZE) methods as I believed they
are defined to do exactly the same thing.
