Only 1 version?

Is everything else discoverable or implied by this? Cache sizes, 
instruction set features, bugs, etc.?

Ideally, this should be based on some h/w id, but generally only SMP 
processors have that.

BTW, is SMP supported? If so, you need to define how secondary cores get 
booted (unless that is standard and implied).
