Here the clock rate should be 1000 times slower, for v3.

This is not the same value as before, but given that the manual states this
value and that AC97 clock's rate is not used by its driver (probably because the
clock is driven by the codec if I remember correctly), that will stay this way.

Here to clock rate is 10 times too quick, for v3.

Cheers.
