In case of P-M (Banias), speedstep does work differently, and this will not work.
Be sure to disable speedstep stuff in such case (or implement it).

SpeedStep also work if ICH-2M, and it is easy to add it in your patch (but
probably not the deeper sleep stuff though, especially if you have an
older PIII, but sleep should be ok).
