Subject: Using speed step with a Pentium III.
Date: Mon, 18 May 2009 21:29:00 +0100
I can not make speed step work with my Toshiba Protege 7200.
My laptop has a Pentium III (Coppermine) processor.
I'm sure it can use speedstep because I used throttling software under Windows.
My kernel version is 2.6.28-gentoo-r5.

Running "modprobe speedstep-lib" does not return any output and the exit code is 1.
Using modprobe on speedstep-smi and speedstep-ich returns "FATAL: Error inserting speedstep_* (FilePath) No such device" and the exit code is 0.

test-laptop ~ # lsmod | grep speed
speedstep_lib           7200  0 

test-laptop ~ # cat /proc/acpi/processor/CPU0/throttling

Report errors and bugs to linux@..., please.
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
