What I would like is the automatic behaviour where the CPU is downclocked to 50% under no load, found under Windows/Linux and I would also like to know why estctrl isn't supported under amd64. I already contacted Colin. :) Gabriel > > Maybe this comment says why (from .../sys/i386/cpufreq/est.c)? > > /* > * Frequency (MHz) and voltage (mV) settings.
