Speedstep doesn't work on Centrino notebooks for Fedora Core 6

[Julian Yap]

Hi,

I have a Dell Inspiron 6000 notebook.

I'm running a Intel(R) Pentium(R) M processor 1.73GHz CPU.

I noticed during boot up, I get an error that can be reproduced when I try
and start up the cpuspeed service.

# /etc/init.d/cpuspeed start
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.18-1.2798.fc6
/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

I've noticed that Fedora doesn't include the speedstep-centrino.ko module.
Normally it would be located in:
/lib/modules/2.6.18-1.2798.fc6/kernel/arch/i386/kernel/cpu/cpufreq/

Would this be the issue?

There's a few bugs in Bugzilla if you search for acpi_cpufreq in Summary.

This bug prevents the CPU from stepping down the lower speed (thus running
all the time at the full speed).

Regards,
Julian
