That's the problem: I want to use "ondemand" but I don't know if it will work properly with my CPU because I don't know if my CPU switches frequency fast or slow :( I can find that information, although the Kconfig file for cpufreq says that AMD64 has latency problems (but I can confirm that, I'm afraid).
