Well, PowerBooks with keyboard backlight, have 2 light sensors (one in
each side, near the speakers), so you can sense the amount of light.
With these information, you can adjust keyboard backlight intensity and
LCD bright dinamically. For example, right now, I am in my bedroom with
no lights, so the keyboard backlight is at maximun level and LCD bright
is at level 3 :)

The program checks every 0.4 seconds and adjust LCD level automatically
