With the ACPI driver (and CPU governor "ondemand") the output of powertop looked always fine.
However with the P-State driver I do now have this output at 2 hardened 64 bit Gentoo Linux systems:
PowerTOP 2.6 Overview Idle stats Frequency stats Device stats Tunables
Package | Core | CPU 0 CPU 1

| 2.60 GHz 8.9% | 2.60 GHz 0.1% 8.9%
| 2.90 GHz 69.1% | 2.90 GHz 62.9% 62.5%
Is this (partly ?) related to the kernel or just an issue of powertop ?
