Hello,
Just for the record, I get the same problem here with powertop 1.13 on
an HP 6730b laptop with the Squeeze's 2.6.32 kernel :
PowerTOP 1.13 (C) 2007 - 2010 Intel Corporation
Collecting data for 15 seconds
CnAvg residency
C0 (cpu running)( 4.4%)
C0
My last post is wrong. acpitool is right.
i am sorry. I should learn the basics in physics.
Since acpitool reports the value in miliamper it has to be multiplied with volt
(which is 20 on my AC adapter) to get the usage in watts.

This seems to be an acpi problem, since acpitool reports the same wrong value.
~$ acpitool -B
