since upgrading to Lucid Lynx powerdevil is unable to control screen brightness 
on Lenovo Thinkpad T60p
when changing power profile (e.g. "Performance" to "Powersave") 
brightness/backlight will de set to level 0
using slider in battery plasmoid will set brightness to 0 too

Fn + Pos1 / Fn + End buttons do work
changing brighness from command line working too:
sudo bash -c "echo 'level 7' > /proc/acpi/ibm/brightness" 

workaround is reported in kubuntu forum:
http://kubuntuforums.net/forums/index.php?topic=3111005.0
that post also says bug came with kernel 2.6.32-19


I'm currently running kernel 2.6.32-24
