I cann't reproduce issue by using a HP machine:

HP openSUSE 11.4 2.6.37.1-1.2-desktop i586 kernel
battery discharge brightness level one wifi off Desktop 3D
effect enabled
powertop 11.3
boot after 10 minues: 7.5 W long term: 10.8W

HP openSUSE 11.4 3.0.4-43.3-desktop i586 kernel (openSUSE:Tumbleweed)
battery discharge brightness lowest level wifi off Desktop 3D
effect enabled
powertop 11.3
boot after 10 minutes: 8.5 W long term: 10.3W
AC Plug-in power monitor(removed battery): 12 W


Didn't have big difference between 2.6.37.1-1 and 3.0.4 kernel.

The HP machine's VGA is: 8086:0116
