transmeta decided years before intel and amd that a constant rate tsc 
(unaffected by P-state) was the only sane choice.  on transmeta cpus the 
tsc increments at the maximum cpu frequency no matter what the P-state 
(and no matter what longrun is doing behind the kernel's back).

mind you, many people thought this was a crazy choice at the time...
