Filtering on GPU is a bad idea because I think there is also computers
with nvidia chip and correct acpi implementation.
You're right for num_levels.
I have the same problem of brighness going to 0 then going to the right brightness. It seems to be a gnome-power-manager bug (I don't have this bug on previous version, and I just reinstalled my patch on my Feisty).
If you are interested, I have debug trace of the instructions send to hal by gnome-power-manager (you can see it by yourself by
sudo killall hald
sudo hald --daemon=no --verbose=yes
) => there is a lot of brightness update starting from 0 value.
