Hello all,

as already discovered by many others, the dothan core pentium m's are
fixed to frequencys listed by ACPI.

Patching the speedstep-centrino.c and turning off
CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI mostly resulted in a non-working
cpufreq module.

The attached speedstep-centrino.c incorperates the sysfs-patch from
http://avkrok.net to dynamically change the Vcore and I added the 08
stepping revision which was neccesary to run cpufreq on my platform.

The file also enables frequencys below 600 MHz for the Pentium M 725
(see lines beginning from 265). Works pretty nice, but enhances the
battery life only a little bit (+20 Minutes on my first run fixed to
100Mhz).

Kind regards from Germany,
	Sascha Kloß
