<p><b>Notes:</b>
Although power management events are often asynchronous, notification
will not be made until polled via this call to permit software to
only receive event notification when it is prepared to process
power management events; since these events are not very time-
critical, it should be sufficient to poll once or twice per second.
The critical resume notification is made after the system resumes
from an emergency suspension; normally, the system BIOS only notifies
its partner that it wishes to suspend and relies on the partner to
actually request the suspension, but no notification is made on an
emergency suspension.
Should not be called from within a hardware interrupt handler to avoid
reentrance problems
