[PATCH] Rewritten backlight infrastructure for portable Apple computers
This patch contains a total rewrite of the backlight infrastructure for portable Apple computers. Backward compatibility is retained. A sysfs interface allows userland to control the brightness with more steps than before. Userland is allowed to upload a brightness curve for different monitors, similar to Mac OS X.
