Tested on my Thinkpad R40 : Radeon 7500.  Is it supposed to consume a
LOT of cpu?  Perhaps there's something funny with -O2 or similar
because some things are VERY slow.  I have not, however, noticed any
major bugs, but screen redraws will take ~1 second if the screen is
not cleared and thus causes powerd to kick my processor up to full
speed often.  Also, the screensaver (logo_saver) seems to take a while
to display.  The screen goes black for 10 - 15 seconds before the
screen saver displays.  Through all this, though, it's still so worth
it.
