I fully agree with what you say about the Opteron. But it doesn't contradict
what I said. Every user of such a system will more than likely also need or
want to run a 32bit binary on such a machine at some stage, and it is just too
restrictive not to be able to do that. It is clear that you want to run 64bit
whenever you can, but you won't always be able to.
