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. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
