So, if you seriously want to do this, can you

1) write specification explaining how desktops should poll() the
brightness files

2) get someone to volunteer to implement that specification for at
least GNOME and KDE?

Hm... Probably I should try to implement it myself :-) and look deeply
what I'm proposing...

Hans, you probably already did some changes for hw brightness changed
attribute... Do you have some links or application parts which handle
this for GNOME, KDE or other DE? So I could look at correct application?

IIRC KDE4 uses upowerd for controlling keyboard backlight.

Gnome uses upower too, and current upower master has patches to
support brightness_hw_changed which you could use as a start.
