I found this thread: 
<http://lists.freebsd.org/mailman/htdig/freebsd-amd64/2004-September/thread.html#2110>
which shows that there are people using the i386 version on the AMD64. It 
makes sense, since there aren't dedicated amd64 versions of windows 
applications. 

I must admit, I'd forgoten it has it's own FreBSD installation ISOs, so I 
guess there is no smooth upgrade path from i386 to amd64. Maybe I'll do that 
with 5.4.
