I was looking at the same thing for FaD. Although I was planning on using it at close to intended speed. My goal is to run as low of a voltage as possible to achieve low heat and power consumption. My Athlon64 and GeForce 6800 just chew up too much power to be on 24/7! As you probably already know, these processors are the same as the normal XP's, but they can run on lower voltages through AMD testing. They are the cream of the crop. So if anything is able to overclock well, it should be on the mobile side.
