For the Intel chips up to and including the Pentium 4 licensing a chipset would not be an issue. VIA made chipsets back when those products were new. I think there was a lawsuit about it, but VIA prevailed. You could license the chipset from them, then use it with an authentic Intel CPU.

But to your original point: CPUs don't really fail unless abused is my understanding. The bad ones are filtered out at the factory before they ever get to consumers.
