I run low power workstations here which are intended to be used in a lab
environment, and I would very much like to have working power-saving
features (otherwise the whole setup is quite useless).
Can I somehow help debugging this, should I file a PR or are there any
further recommended things to do?
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.
