Bug Description

Fn + F1/F2 are supposed to change the brightness of the LCD screen on Macbook (rev. 2). They weren't supported on Edgy (the pommed daemon made them work anyway, outside of Gnome). When upgrading to Feisty on of the (many) good surprise, was that it was working flawlessly (with the gnome OSD).

Since the last week update (may 07) on Feisty (with a lot of stuff related to hal), it doesn't work anymore (so pommed has to be launched as startup again, no more gnome OSD though).

Keycode are 101 (Fn-F1 = brightness down) and 212 (Fn-F2 = brightness up), as reported by xev.

I can confirm this, when installing (and after the first boot), the F1/F2 keys work well. After updating it, i'm unable to use it anymore. I have a MacBook model MA700LL/A.
