What do you mean? Suspend affects everything, because we're about to turn
off the chip (the oldstate stuff is a thinko). If we're in the middle of
telling the chip to lock/unlock then suspend has return failure till we're
finished.

Hmmm. Better to design the API better so it can describe the capabilities
of the chip. You don't have to stick to what I threw together - I'm full
of crap half the time. Hadn't you realised that yet?
