After another test on my part, I discovered that I am not seeing a freeze
on hotplugging. Probably put this iBook to sleep before I plugged the CD
burner in, and the FireWire controller was already a lost cause.

Also, a heads up - I've found that unloading 'ohci1394' before suspend and
reloading it after yields a working system, no freezes after unsuspend. At
least on this FireWire iBook, anyway. If I don't, the system hangs after
unsuspending as soon as a FireWire device is accessed. May be useful for
suspend handling in the driver itself.
