I recently found an old system that had no cpufreq capability other than p4-clockmod. When on the performance governor it runs at its full 3 GHz. When on powersave, it drops to 375kHz. While this makes a big difference under load, when the system is idle I can not measure any power or thermal savings.
In other words, p4-clockmod seems to be useless since lowering the cpu frequency without lowering its voltage does not save any more power than simply being idle and in the HLT state.
