Is it the latest kernel update I installed on my Gentoo Box (suspend2-sources-2.6.16-r8) or the newly updated xorg-server-1.1.0? Today I recognized while writing some text, that my power consumtion indicator of KThinkBat displays 14 W. And this battery powered and with lightest display backlight. Normaly, it needs arround 17/18 W.
This is great news - my ThinkPad lasts noticably longer on battery power than before.
