I have a MacBook Pro 5,1 and my LCD backlight stopped working in Karmic after some package update a couple months ago. The Fn keys work but as the notification bubble brightness bar changes, the LCD backlight brightness does not change (it's fixed at the maximum level).
I inserted the mbp_nvidia_bl kernel module and voila! I can echo N to /sys/class/backlight/mbp_backlight/brightness to now adjust it. However, the Fn keys have no effect.
