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

Log Message:
Keep track of current power state (resumed, standing by, suspended), and
only perform standby/suspend/resume actions if the state actually changes.

Inspired by some similar code in the USB code, pulled into here so that
the workaround isn't needed in every driver.
