	syssrc/sys/arch/i386/i386: apm.c

Log Message:
fix problem detected on IBM thinkpads when running apmd:
	when the display is closed, the machine suspends (as expected).
	when the display is opened again, it resumes and suspends again
	(must manually wake).

problem happens because driver fills the event queue with duplicate
events without allowing apmd to drain it by running.   fix it by
improving detection of duplicate events.

also cleanup and add some extra APMDEBUG code.
