this is the BIOS instructing us to run slower,
so AFAICS we are doing the right thing.

We've seen several machines with BIOS that use PPC update
to manage thermals, eg the T60.  What box is this, and
where is its acpidump?  Did it not heat up in previous releases?
Is the fan spinning at full speed when this happens?
(has it recently become clogged?)
