But min=max=freq is awful... I know, I reccommended it sometimes, but with the appearance of the userspace governor (already available on the cpufreq homepage, http://www.brodo.de/cpufreq/advanced.html , will be submitted soon) min=max=freq is deprecated.

It should be common for at least Intel and AMD, no? No. Intel doesn't let you select the exact voltage. IIRC, only vew VIA/Cyrix-longhaul-capable processors and, of course, powernow-k7 are vaild targets for such a patch.
