64-bit mirrors

Folks,

I've been working for the past couple of months on building a new machine for
pgFoundry and to be a PostgreSQL mirror.  It's hard for me to justify,
though, NOT going Opteron.

So, my question is, if I put pgFoundry on an Opteron machine, is there another
64-bit machine in the postgresql network I could mirror it to in case of
failure?  This seems better to me than letting our 32-bit dependancy drag on
because we can't afford to upgrade all the machines at once.
