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.
