To me , it looks like he is using the factory speed. These CPUs run 
usually at 800Mhz to save power when using battery power and 1800Mhz 
otherwise.
What he has done is simply enabling something that should just work , 
but with the kernel rpm didnt... I bet if he boots to the other OS (if 
he has it) , it'll be using the same speeds (800Mhz with battery power , 
1800Mhz otherwise).
