Hi Stephane,
Thanks for the info. I really believe you :-)
The X keycodes are indeed 129-132. I checked them using xev.
I checked /proc/i8k while pressing the buttons next to the
power button and they work fine.
So what's left is to tie these buttons to some function so that
I can control the soundvolume/dvd player wherever I am i X...
