Just updated to latest kernel again. No change.

clickwir at lappy:~$ sudo modprobe powernow-k8
FATAL: Error inserting powernow_k8 (/lib/modules/2.6.24-19-generic/kernel/arch/x86/kernel/cpu/cpufreq/powernow-k8.ko): No such device

powernowd: Found 1 scalable unit:  -- 1 'CPU' per scalable unit

PowerNowd encountered and error and could not start.
Please make sure that:
 - You are running a v2.6.7 kernel or later
 - That you have sysfs mounted /sys
 - That you have the core cpufreq and cpufreq-userspace
   modules loaded into your kernel
 - That you have the cpufreq driver for your cpu loaded,
   (for example: powernow-k7), and that it works. Check
   'dmesg' for errors.
If all of the above are true, and you still have problems,
please email the author: clemej at alum.rpi.edu
