Subject: pwoertop frequencies not ordered descending

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:

Is this (partly ?) related to the kernel or just an issue of powertop ?
