Bug Description
1) Kubuntu maverick beta
2) 2.6.35.19.20 0
3) Pressing the brightness keys should increase/decrease the brightness by 1 step
4) Pressing brightness-down decreases brightness by two steps, pressing brightness-up increases the brightness for a split-second, then decreases it back to what it was. It's impossible to increase brightness using the keys, I have to increase by other means (powerdevil slider, xrandr --set, etc..)
Hardware: Notebook Fujitsu-Siemens Esprimo mobile U9200 (intel GM965)
Annotated showkey - s output:

Mainline kernel (2.6.35- 02063503- generic #201008211321 SMP Sat Aug 21 13:24:00 UTC 2010) behaves the same way.
My messenger log reveals that this apparently worked in an early maverick daily build (2010-06-27 or thereabout), shortly before alpha 2 - is there any way to get it now so I can check?
