Ok, I'll stay tuned on this and report back with X 1.5

In 2.6.25 there's a brightness_switch_enable for video module, which
can be used to tell kernel not to mess with the brightness, and just warn u=
serspace.
When this is set, I can run gnome-power-manager to manage the
brightness, and it correctly catch brightness keys, so it works.

What I'd like is to manage this in the kernel, but it's not really
related to this bug, so I'll check on that later, when it's fixed.

Cheers, and thanks for your time.
