Thanks for clearing it out for us all, but the fact is that Pentium
4 M (not Pentium M from Centrino "toolkit") is capable of SpeedStep
(Not Enhanced SpeedStep, right?). But freebsd lacks of speedstep support 
(AFAIK, hw.acpi.cpu_throttle_state plays only with processor C-states,
which are not SpeedStep),  so I'm womdering if est.ko would do
something with Pentium 4 M processors.
