Actually, the number for processor speed that you normally see posted 
(and the number that I've apparently been using so far in my 
machine-status document) is the data bus speed, not actually the CPU 
speed.  However, since I think that the bus is the limiting factor, we 
might as well leave it that way, unless someone has a convincing argument 
for going the other way ;-)
