At least of the Xeon Intel has documents that specific to the model
of cpu you are using.  And the values where in there.

I don't think this is speed step technology as it requires a reboot 
to change the clock multiplier.  You might also want
to look at msrs 0x2c && 0x2d.  I don't have these totally figured
but it looks like on the newer Xeons these controll the cpu frequency,
instead of the strap values on the cpu.
