In the setup.c seems about right ;)

Correct me if I'm wrong, but can you change the processor you have (while it's running) ? Ok, so how about at the same point that the i386/i486/P5/P6 stuff is messed with ?

I don't see the probelm with having it in the kernel, like all the intel stuff (I would like to see the Cyrix/IBM/NextGen/... support there too).
