p4tcc0 reduce only frequency (actually it wont reduce the core frequency), but not core voltage. You actually wont save a lot of power with it. It's main usage is to reduce processor temperature if need be. The cpufreq0 actually is not a real driver. It's used to merge different drivers (for example p4tcc0 and est0 if your processor support SpeedStep) in order to provide an unified interface available via dev.cpu.0.
