Michael Hanselmann 5474c120aa [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.
