Owners of the awesome 17" PowerBook would all agree the backlit keyboard is even more convenient than first thought. But it does have a nasty quirk - as with the display's ability to self-adjust its brightness, the keyboard will likewise illuminate at a brightness based on room lighting. The problem is if you're in a dimly lit room the backlight will only partially illuminate, causing the lettering light up grey - and grey text on grey keys is rather difficult to read. Thus one is either constantly turning the brightness back up (since it will keep turning itself back down) or just turning it off entirely (at least the black lettering will be a little easier to read).
The solution is to force the backlight to be 100% whenever it's on - by making the minimum light level 100%. Pop into /Users -> your_username -> Library -> Preferences, and open com.apple.bezelservice.plist. Change the value of kHWMin to 1 and you're done! Be careful playing with the other settings though -- until I finally got this right, I was causing my backlight to either be stuck on permanently, not work at all, or (get this!) it was turning ON in the light and turning OFF in the dark!
