brightness keys not working on macbook 3.1

Bug Description

I installed Ubuntu 7.10 Gutsy with kernel 2.6.22-14-generic, both i386 and amd64 on my macbook 3.1. The brightness controls are not working. I have tried with/without fn key+f1, <ctrl>+f1, fn key + <ctrl> + f1.
I also installed the apple keyboard patch but although the patch enabled the fn key, the brightness controls still don't work. I also tried
installing pommed v1.11 but even that has no effect. I tried with fn=1 and fn=2 (in pommed.conf)

My macbook has Intel GMA x3100 for processing graphics while pommed.conf has only gma950 in it.

PS - On the bootup of my newly compiled kernel, it says

i8042.c: No controller found

I compiled the kernel by getting the kernel source through - apt-get linux-source,
installed the mactel updates and the keyboard and touchpad patches. I also changed the
processor type to Core 2/New Xeon
The touchpad patch seems to be working fine.
Keyboard layout is Macbook/Macbook Pro

"/usr/share/hal/fdi/policy/10osvendor/10-macbook-backlight.fdi" needs to be updated to recognize the keys. Patch attached.

This does not actually adjust the brightness, however. That still needs to be fixed.

Just an update to note that xbacklight can correctly change the brightness..

pommed from svn can correctly change the screen brightness
