It occurs to me that it might be useful to have only one core that is
x86-compatible, and the rest using an architecture that can be optimized
for die area and power dissipation without being constrained by backward
compatibility. (In fact, the Cell processor is not too dissimilar to this,
with PPC instead of x86.)
