Brightness control of NC10 causes screen flashing

[Jon Grossart]

While booting and during initial setup, the brightness control keeps alternating between high and low settings causing the screen to flickr. By setting the brightness manually, you can get it to stop for awhile, but it will occasionally start up again.
