setting CPU voltage with cpufreq/cpufreqd


Has anyone tried changing the voltage for their CPU using either cpufreq or cpufreqd? Google does not seem to want to be my friend on this one.

I dont necessarily mean scaling the voltage dynamically.

There's a nifty program I use on Win XP called Centrino Hardware Control. Aside from letting me switch power profiles, it also lets me set the voltages for the different multipliers of my Pentium M. I use voltages lower than the stock voltage settings and as a result I get lower temperatures and more battery life. I was just wondering if there's something in Linux that can do the same (i.e. something that lets me change the stock voltage for the different CPU frequencies).
