maybe relevant: I have upgraded my BIOS to the newest and none of cpufreq modules were able to load.
The cpufreq was always: 598MHz.

It works on my T42 with the 1.8 GHz version of this processor, using
lenny, squeeze and sid kernel versions. The BIOS version is 3.05a.
Maybe there was a regression in a later BIOS version?

Ben.
BIOS Version 3.23 (1RETDRWW)
BIOS Date 2007-06-18
Embedded Controller Version 3.03
CPU Type Intel(R) Pentium(R) M processr,
CPU Speed 1.53GHz
Changing BIOS setting from Slow to Max custom setting changes time between
"Grub loading." to "Welcome to GRUB!" from 15 to 5 cursor blinks :).
However, when system is loaded then mprime benchmark shows exactly the same (SLOW) result regardless of BIOS setting.
System initiation changes the frequency to the lowest one.
Loading patched speedstep-centrino module causes mprime benchmark faster results.

Please see
http://support.lenovo.com/en_US/downloads/detail.page?&LegacyDocID=MIGR-50273#summary
which says
"Note: This BIOS version will only work with Embedded Controller
Program Version 3.04 (or higher)."
This may explain your issues unless the values above are a result of a
typo.

Previously you said 1.73 GHz... and Wikipedia doesn't mention a 1.53 GHz
version so I think that was correct.
Is 'Intel(R) SpeedStep technology' enabled in the BIOS?
Have you run any other kernel version or distribution, in which the
acpi-cpufreq driver?
Ben.
Grzegorz Kochański
sorry for so not long responding,
I was fighting with Embedded Controller Version 3.03 and finally it is 3.04, but nothing else has changed.
I did not make a mistake BIOS presents:
CPU Speed 1.53GHz
what is the source of /proc/cpuinfo ?
when I load and unload patched speedstep-centrino module /proc/cpuinfo stucked with single frequency, even it was changed by ondemand kernel governor.
so it seems to be still BIOS problem...

I have tried, many BIOS versions compatible with
including Embeded Controller 3.03 (e.g. 3.05a mentioned by you) but
during downgrading for BIOS below 3.12 I always get:
"CPU ID is not correct for this system."
Lenovo support does not recognize their hardware.
type: 2374-g1g does not exists for them.
So it seems I sucked with this issue.
Thank you for your attention.
Please close the issue,
I will use patched speedstep-centrino for myself only.

Why not upgrade the Embedded Controller Program first, and then the
BIOS, as described at [1]?
