I'm installing Opensuse 10.0 on Siemens Fujitsu Lifebook S7020 and I'm
not able to setup CPU throttling. Looks like kernel doesn't support it:

# cat /proc/acpi/processor/CPU0/throttling
<not supported>

I have tried modules acpi-cpufreq and speedstep-centrino with the same
result - CPU frequency can be changed, but throttling is not supported.

Processor is
Intel(R) Pentium(R) M processor 2.00GHz, motherboard with intel 915

Any idea what's missing?

I believe that they (Pentium M's) don't have throttling at all.

You are right - thermal throttling is supported only in
Northwood and Prescott cores. Sonoma type in intel 915 MB doesn't support it :-(
