Comment 18 for bug 337945

After more searching regarding this same issue seen in Intrepid it seems there was a gnome-power-manager provided in the PPA to help address light-sensor readings adjusting the brightness of keyboard backlight.
I've also tried mucking around in this file /usr/share/hal/fdi/information/10freedesktop/10-applesmc.fdi
and this one /usr/share/hal/fdi/policy/10osvendor/10-macbookpro-utils.fdi

but didn't successfully accomplish anything. These seem to be the main 2 involved though.
