I must admit that I did not update this machine since some time.

The scripts are still available here

http://www.alogreentechnologies.com/freebsd/XonX220
http://www.alogreentechnologies.com/freebsd/setbrightness

I never tried to bind the script to keys. I made some menu items in
blackbox which works for me.

You lose only 1-2h? I lose at least 2h.

I have had several tries to make it better but got always held up by
other things.

My last attempts have still been with the Crusoe CPU. They gave the
machine near XP battery times but needed manual interaction. So, I
never published them.
