Become root and go to $ cd /sys/class/backlight/$DRIVER where $DRIVER is a sub directory. Just do an ls in /sys/class/backlight to find out. In this directory you find a pseudo file called "brightness". You may run $ echo x > brightness to switch the brightness.

Right. I can't say when exactly it broke but I think all of the alpha releases were fine... must have broken in late beta? @Kirill: Do you have other regressions, too? Like not correctly detecting "on ac" (and showing an empty battery icon)?
