(speedstep-centrino for older 2.6 kernels) and a cpufreq-* module
loaded. In my case, I have the cpufreq-userspace module loaded and let
the powernowd daemon control it in userspace, and this works great.
This enabled me to turn it on and off whenever I want, and also set it
to a frequency myself. Also, depending on what type of Pentium M
you've got (banias, dothan, sonoma, 400 or 533mhz fsb) you may need to
have a recenty kernel (2.6.11+) for it to work well.
To check if speedstep is working, let the laptop be idle and do cat
/proc/cpuinfo. If it returns a frequency that is significantly lower
than the max frequency, it's working.

- A C600 with Ubuntu Breezy did the same, in the end I disabled
speedstep in the BIOS to 'shut it up'.
Having said that I was using Kubuntu (Hoary) a while ago which was
configured out of the box to switch into standby - working fine
otherwise as well.
