Ho hum. Greg, any preferences? We can either:

a) Add a `restart' driver method and call that during reboot instead of
->shutdown, if the driver implements ->restart. Otherwise call
->shutdown or

b) stick with the

if (system_state == SYSTEM_RESTART)

thing in IDE and potentially a couple of other places?
