K -> System -> KSysGuard shows a display of 4 system performance parameters. I deleted the Swap display (as the swap partition hasn't been touched yet) and added a display of the CPU Clock frequency sensor. It was 600 MHz.

Running powernowd in a Konsole lists several parameters of the Pentium M processor can be adjusted. It's a little cryptic, but running:

sudo powernowd -v

(and entering the password) shows the present parameters. In my case, the CPU could run at 600 - 1700 MHz in 200 MHz steps (except for 300 MHz at the last step). I'm not sure what I did exactly, in changing the "s" option to 1 and then back to 100000 kHz caused the CPU graph to go to 1700 MHz and the Power Manager thingy on the KDE Panel to also indicate 1700 MHz.

I don't know if this setting is sticky or not. I'll revise this post if/when I learn more about the powernowd settings.

Cheers,
Scott.
(Who is under the impression that powernowd is designed for AMD processors so is curious why it works at all with this Intel chip.)
