Comment(by dilinger):

 Ok, the reason we weren't seeing power button events on wakeup was because
 we were clearing PM1_STS in the resume path.  The reason we were doing
 that was to fix (I believe #2426); we'd wake up, see that the power button
 had been pressed, send the event to userspace, and userspace would then
 tell us to go right back to sleep.
