A possible optimization would be to map the video card > memory into the space. 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. -- If I write a signature, my emails will appear more personalised.
