Comment 189 for bug 524281

This bug I suppose is the root cause of the second power consumption regression found here:
http://www.phoronix.com/scan.php?page=article&item=linux_kernel_regress2

Basically power usage looks like:
- 2.6.24-2.6.34: average of all tests ~21-22W
- 2.6.35-2.6.37: average of all tests ~25W
- 2.6.38-2.6.39: average of all tests ~26W

This translates into laptop operation times under test workload:
mAh V W mA h
