When i start my KDE session, guidance-power-manager.py crashes with the
attached traceback.

It appears to be trying to read from
/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq , which does not
exist on my system.  The contents of
/sys/devices/system/cpu/cpu0/cpufreq/ are as follows:

--------------------
$ ls -lF /sys/devices/system/cpu/cpu0/cpufreq/
total 0
-r--r--r-- 1 root root 4096 2006-11-06 19:09 affected_cpus

-rw-r--r-- 1 root root 4096 2006-11-06 19:09 scaling_min_freq
--------------------

(Note that i am using /usr/bin/longrun to control the power
characteristics of my Transmeta processor).

Looks to me as if guidance-power-manager should handle this condition
more gracefully.
