Thanks for the answer. Here are the updates:
----------------------------- % modprobe thermal && echo OK OK
% cpufreq-info cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to linux@brodo.de, please. analyzing CPU 0: no or unknown cpufreq driver is active on this CPU
% source /usr/bin/cpufreq-detect.sh
% echo $MODULE powernow-k8
% modprobe $MODULE FATAL: Error inserting powernow_k8 (/lib/modules/2.6.20-grml/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device
% dir /lib/modules/2.6.20-grml/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko -rw-r--r-- 1 root root 15387 05-03 15:10 /lib/modules/2.6.20-grml/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko
% cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No such file or directory
% ls /sys/devices/system/cpu/cpu0/cpufreq No such file or directory -----------------------------
To recap, the problems I see are:
- The thermal kernel loaded ok, but cpufreq-info still says no driver is active
- cpufreq-detect.sh successfully detected my CPU module, but modprobe return weird error "No such device".
Here are more testing/info:
----------------------------- % mkdir /sys/devices/system/cpu/cpu0/cpufreq mkdir: cannot create directory `/sys/devices/system/cpu/cpu0/cpufreq': Operation not permitted
% /etc/init.d/powernowd start Starting powernowd: required sysfs objects not found!
$ grep sysfs /etc/fstab sysfs /sys sysfs defaults 0 0
# just shooting into the dark % modprobe cpufreq_userspace && echo OK OK # afterward, cpufreq-info returns the same
% cat /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file should contain the names of kernel modules that are # to be loaded at boot time, one per line. Comments begin with # a `#', and everything on the line after them are ignored.

BTW, anybody know the 'conservative' governor?
Yes. ;) But I usually prefer the ondemand governor.
Just FYI, seems that conservative is newer than ondemand:
http://www.linuxfromscratch.org/hints/downloads/files/cpufreq.txt : As of 2.6.9, an 'ondemand' driver was made available. Other demand-based governors, such as 'conservative', have been introduced in later kernels.
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/doc/OLS2006-ondemand... : conservative governor is a fork of the ondemand governor with a slightly different algorithm to decide on the target frequency. Most of the configuration details of ondemand in this paper also holds true for the conservative governor.
Of course, newer might not grantee better. :-)
