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

Sorry, I pointed to it because I am ignorant about thinkpad firmware.
It was the page I referred to when looking this stuff up.

If there is a way for speedstep-centrino to safely support these CPUs
on a variety of machines, it would be nice to do it.  That would mean
less fuss for people with broken BIOSen, which are of course not rare.

And on the other hand if this BIOS bug is a common one and unfixed in
the latest version, it would be nice to put up fixed tables on some
thinkpad-related site, so people could easily override the BIOS and
fix it for themselves that way.

In an ideal world, the order of events would be:

 - understand and fix the BIOS bug
 - understand and mitigate any risks of the speedstep-centrino patch
 - apply the patch

However, we seem to be stuck at step 1.  I guess it's best to wait
until someone else reports similar problems before spending more of
your time on this.

Doing so.  If you learn more, please keep us posted.

Here's some old discussions about the fundamental problem with the
hardcoded tables and possible ways to solve it:

 http://thread.gmane.org/gmane.linux.acpi.devel/12273
 http://thread.gmane.org/gmane.linux.acpi.devel/46427/focus=46439

I believe it should be possible to make progress by sending a
description of the symptoms and "acpidump" output to
<linux-acpi@vger.kernel.org>.

Thanks,
Jonathan
