Hm, strange, works fine here on t61p , standard archlinux kernel, nothing
out of the ordinary.

I've similar problem here with my X60s.
echo 'up' >! /proc/acpi/ibm/brightness
works fine but using the hotkeys has no effect. I now realized that xev doesn't return a keycode for FN+HOME and FN+END at all. FN only gives a keycode as well as HOME and END on its own do.
However, i'm using Vanilla, so don't expect this to be an arch related problem. AFAIK things concerning brightness adjustment changed for 2.6.29 in the acpi/video branch.

did anyone solve the problem?

So pressing the fn home/end for brightness alters :

doing an:
echo '100' >/proc/acpi/video/VID/LCD0/brightness
My .config for the kernel is set to:

kernel is 2.6.29-ARCH
anyone know why the brightness still refuses to work?
