CPU scaling on Intel Centrino Duo?

[Duncan Lithgow]

I've been wondering about this for a while... I maintain a laptop test
for my laptop
(https://wiki.ubuntu.com/LaptopTestingTeam/HP_Pavilion_DV8220EA) but
I've never been able to find out just what range of CPU scaling my
processor _should_ support. It's always got some scaling, but I don't
know if that's the right amount - can someone help me?
