There's an important item you missed.  Drivers need to supply positive
acknowledgement before a suspend happens.  If there are drivers
incapable of suspending properly, the system should not suspend -- you
should never see "the machine woke up, but XXX doesn't work any more".
Preferrably, the architecture for this should inform the user *which*
devices failed.
