I've now discovered
/lib/modules/<kernel name>/kernel/arch/i386/kernel/cpu/cpufreq
so I know the options.
I've tried most in the list - not the ones that are obviously
inappropriate, at least, obviously inappropriate by their name - and I'm
trying to discover how to uncover which is the best and why.
If this is written down anywhere, then I'd love to know.
