Maybe KDE is in the path.

The "legacy" part was necessary on -rc7 or 8, I don't remember. I'm using an
2.6.25+thinkpad-acpi patch, and still no real success, except with xbacklight.
What I need is to hack some stuff in powersaved so it can talk to xbacklight
when brightness keys are pressed, I guess.
