Apparently something is broken within KDE here. I just checked, and I don't 
have the support for CPU scaling. And I sort-of remember having it before (on 
the same hardware). IIRC it would scale the frequency down when in powersave 
mode (ie. when I run it on batteries).

Let me check...

Well, frequency scaling actually *works*, just checked by (un)plugging and 
reading /proc/cpuinfo, it does scale from 1.5 GHz to 1 GHz when on batteries. 
It seems that just the PowerDevil GUI is broken and doesn't allow you to 
choose any settings. In systemsettings -> Advanced -> Power Management -> Edit 
profiles -> CPU and System, the "CPU frequency scaling policy" drop-down box is 
empty and does not provide any options to set up, while in Capabilities tab it 
says that I don't have any scaling capability.

But it does actually work, ie. it does scale the frequency when (un)plugged or 
when swithcing profiles.

At least this is the situation on my machine.

HTH, :-)
