reuben just reminded me that it might be worth mentioning the
user-visible changes that come about as a result of the switch to
powerd from ohmd.  there aren't many, at least as powerd is
currently configured:

    - new shutdown "menu" screen when the power button is pushed: 
	i take full responsibility for the graphics [1], and any
	suggestions for improvement will be seriously considered. 

	there are three possible actions:  a) do nothing, and the
	system will sleep in 7 seconds, or b) hit the keyboard or
	touchpad to cancel and keep working, or c) push the power
	button again to shut the laptop down (cleanly).  the goal
	is to break the "hold the button for 4 seconds" habit.

    - the idle timers are set so the laptop will idle-suspend after
	15 seconds, the screen will dim after 60, and the laptop
	will sleep after 4 minutes (all counting from last
	keyboard activity).  are these appropriate for a classroom
	and student setting?

    - if on battery, the laptop will auto-shutdown after its been
	asleep for 1 hour.  if plugged in, it will sleep forever.

    better centered on the XO screen)
