HP Omnibook model number f1662wt. I guarantee this thing peaks out at
450MHz (448.055, actually). GenuineIntel processor 0 family 6 model 8
stepping 1. Pentium III (Coppermine) with 256kb of cache.

While I'm not calling you a liar, I am saying that I'm not imagining it.
This could be an HP 'special' where they took a 500 and ran it at 450.
Or any other such thing. If it's not using SpeedStep, I'm not sure what
it is using.

My current method of speed changing is to reboot the laptop with the AC
plugged in for "high" mode, and unplugged for "low" mode. Once booted,
it doesn't seem to change modes.

I'll retry it a little later tonight, but as I recall, neither
speedstep-smi nor speedstep-ich (which i tried just to see if it was me
being stupid) worked, and complained about some very odd things.

I apologize.
