Running i386 binaries on amd64

[Jim Prettyman]

I have just installed FreeBSD-6.1-R on an athlon64 box, which is my
first ever experience with amd. I was under the impression that the
amd64 machines could run binaries built for the i386, but I'm not
having much luck with the system as it is now.

Am I trying to do something that can't be done? Or is there some magic
that I need to apply first?
