CPU Scaling on Intel Atom 330?
 

Has anyone got cpu scaling on an Intel Atom 330 Processor work?

This is my error message, though the file is there:

# modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.26-1-686-bigmem/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

I have been trying to compile my own kernel to support cpu scaling, but no luck so far.

Some useful links:

Thanks for the reply amani.
Do you have an Intel Atom 330?
Have you been able to compile a kernel that supports acpi_cpufreq for it?

Unfortunately I didn't see anything that really specific to the Atom 330.

The Atom isn't listed in the Processor Family options when I compile the kernel. I've tried 2.6.29.3, which I believe is the latest, twice. Once with generic-x64 as the processor family, and another as core2. Neither of them work and give me the same error message.
