Comment 148 for bug 524281

I have found that this bug is related to X: without that there is no problem!

I have accidentally deleted the nvidia kernel module, thus my laptop booted into text mode. Then I run the powertop dump and the [kernel scheduler] Load balancing tick is down to 1,6 from 64,2 with X with the same official Ubuntu 10.10 2.6.35-22 kernel!
Logs attached, hope this finally helps to fix it!
Should you need more testing contact me.

I think that the importance of the bug should be high, since it makes a vast difference in the battery runtime for all laptop users!
