FATAL: Module acpi_cpufreq not found.

Hey, thanks for the guide, works on Intel Celeron D processors too, clocked mine from 2.8GHz down to 350MHz. Ideal for that home Linux box that sits idle most of the time!

Also:

/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

still reports: ondemand performance, after the changes, have double checked this.

And missing is /etc/sysfs.conf, I have Debian Etch installed.

But it appears to have worked:

$ more /proc/cpuinfo | grep MHz
cpu MHz : 349.991

I wish to keep the blog as general as possible but anyway there will be a strong Debian influence

Excellent explanation and howto. I see this blog is going to be Debian related only.
