I am seeing this same bug on my MacBook Pro 5,1 with Ubuntu 8.10 using
the mactel-support ppa with all relevant packages from the PPA installed
and kernel modules loaded. This includes the updated package of gnome-
power-manager from the PPA, and the only way to fix the problem is to
disable the 'Use ambient light to adjust LCD brightness' option in
g-p-m. Perhaps the light sensor reading is not correct? I am familiar
with linux kernel development and debugging (just not on the MacBook Pro
- this is my first) am just not too sure where to start debugging this
one - any ideas?

i am using a macbook pro 3.1 with intrepid beta and the nvidia driver. i finally managed to have the backlight keys F1 and F2 working but now i face another problem. when i change the backlight setting, it resets itself after some minutes to an average light level. then i use f2 to increase backlight again and some time later it goes down again.i have deactivated the shade setting in the gnome power management. the light is also turned down while moving the mouse or typing.
