The remaining frequencies are:

1597/35000 1463/31000 1330/27000 1197/23000 1064/19000 931/15000

Additionally, I do not remember how many CX states I had before - but I 
am pretty sure that it was more than just one. Now, the only CX state 
remaining is C1/3.

Interestingly, disabling either the p4tcc or the acpi_throttle driver on 
its own does nothing to cut down on frequencies. Only when both are 
disabled via hints does the list drop from 13 frequencies to the 6 above.
