SpeedStep-Problem
Hi,
I have recently bought a new laptop (Intel Pentium M processor) and
tried to test the SpeedStep-function. Therefore, I downloaded the
kernel-source 2.6.7 and compiled it with the "Enhanced SpeedStep"
support. Unfortunately, the following error was reported, as I tried to
load the speedstep-centrino module:
FATAL: Error inserting speedstep_centrino
(/lib/modules/2.6.7-rgw/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko):
No such device
The CPU doesn't seem to be supported, but speedstep works in Windows!

I also have activated CONFIG_X86_SPEEDSTEP_RELAXED_CAP_CHECK in the
kernel, but without success.
Here is an excerpt of my kernel-config:

I am looking forward to your answer!
