For desktop PCs, I guess grouping by CPU type makes sense. But I guess
I'd prefer grouping CPUs by manufacturer, not by CPU "family".

So I'd propose

pc/intel/i486
pc/cyrix/cx486
pc/amd/am486
=2E..

Advantage is, that even if you know little about the chip, you know
who manufactured it and how it is called :-).
