The situation in which I want to change the frequency arises when I'm running one compute-intensive background job per CPU at 'nice 5' so that I get decent performance in interactive jobs as well; it seems that the default governor regards the situation in which niced jobs are using 100% of the CPU as one in which it can happily set the speed down to 1GHz, which is not at all what I want. Possibly fixing that is more like the Right Answer.
