Re: Fan control and CPU temperature etc

Did you compile your kernel with the /proc/cpufreq enable. I know it's
obsolete in 2.6, but I could not make cpufreqd use the sysfs interface

Beware also that the version of cpufreqd in testing has a
missing fclose which makes it run for only 250 seconds. Upstream has
corrected it but it's not yet distributed. Below is the patch if you
want to recompile

I not sure if you really need cpudynd. I don't know exactly what it is adding 
to cpufreqd. But cpufreqd is definitely needed. When cpufreqd is working 
you can see the influence of cpu scaling in /proc/cpuinfo.
