I believe the problem is that our CPUs don't match any of the
identification verification methods performed in
src/sys/i386/cpufreq/est.c.

I should be able to make a patch for this, but will need time  -- our
to-be-dev/test C2D box sits in my living room waiting for CPUs to arrive
so it can be built.  :-)

If you'd like to file a PR in the meantime, that'd be great too; let me
know what the PR # is.
