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.
