The attached patch introduces runtime latency measurement for ICH[234] based chipsets instead of using CPUFREQ_ETERNAL. It includes some sanity checks in case the measured value is out of range and assigns a safe value of 500uSec that should still be enough on problematics chipsets (current testing report values ~200uSec). The measurement is currently done in speedstep_get_freqs in order to avoid further unnecessary transitions and in the hope it'll come handy for SMI also.
