Blame AMD, they're the ones who called the technology AMD64 :)

Because they're based on mips technology, not amd64 technology, and are
never referred to in any AMD documentation as 'AMD64'
At any rate, I think this should be left up to the AMD64 team and not
forced on them via a GLEP. I don't think any architecture
team appreciates being told what's good for it by people who haven't
been dealing with the bugs :)
