Hy,
I generated a custom kernel with make-kpkg command with containing the
Debian report committed patch.
The test now not I doed yet my netbook, but my laptop top showing
following good values:

The interesting result will be my netbook, but possible I need
generating an Amd64 architecture compatible version.
Now used custom kernel version is following with generated make-kpkg
command:
Linux hammera-Satellite-L300 3.2.16 #1 SMP Wed May 23 10:26:26 CEST 2012
i686 i686 i386 GNU/Linux
