Ok, we know that pommed works. addon-macbook-backlight in hal doesn't work. Thats strange, because pommed code and hal code are basically the same for adjusting the Macbook brightness.
The introduction of PolicyKit/ConsoleKit broke that part of code in hal.

I've run hal with more debug information (see attached patch) and got:
[E] addon-macbook-backlight.c:145: failed to mmap: errno:
'Success'

** ERROR **: failed to gain access to the video card
aborting...

I have no idea why this mmap fails.

To those who have a second or higher generation Macbook:
Do you run x86_64? Maybe this just doesn't work on 32bit.
