The gnome-applet says my hardware doesn't either support CPU frequency
scaling or my hardware may be misconfigured.
Which one is correct?

Hi Matthias,
*** That depends a lot on how old the processor is. If you can get a
model number, then you'll have a better chance at finding out if the
processor does support it. Intel uses SpeedStep [1] to do it's
frequency scaling. Since the Celeron M is based on the Pentium M
microarchitecture [2], it looks like it should have SpeedStep. If it it
is a Mobile Celeron instead of a Celeron M, then I don't think it has
any SpeedStep on it. Check out the list of Celeron CPUs at Wikipedia
for more info [3].
