Speedstep problems

I'm trying to get speedstep working on my Q6600, I've followed this guide:
http://wiki.archlinux.org/index.php/SpeedStep

The first alternative with cpudyn sets the govenor to powersave, I've tried blacklisting the powersave module but it doesn't work, it still get loaded. If I do the following:

echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor

It works as it's supposed to, upping the Hz when needed. And I've put this in /etc/rc.local  but after a little while it just changes back to powersave govenor.

So I tried the alternative alternative with cpufreqd, now it seems to set the correct govenor but it doesn't work, it's stuck at 1,6GHz, changing covenor from ondemand to performance doesn't help either.

Re: Speedstep problems

A finally, it seems I have found a solution

edit /etc/conf.d/cpufreq for your requested settings; please note that you can also comment out min_freq and max_freq options, since the kernel already knows those value

I seems that just removing that part was the solution, I had tried setting values in all ways MHz/GHz/exact value, nothing worked, simply commenting them out did it.

EDIT: really bad formating
