Correct, you can set the governor, and also set the limits.  I believe
this is available somewhere in /sys.  Just echo <freq> > /sys/whatever
in whatever local.d or equivalent boot-time script your distro
provides.

I set rules based on temperature, but it still uses the built-in
governor.  That is, the temperature is polled, and when it hits a
limit the application changes the governor settings.
