How do I change to NFS version 3 so that other UNIX variants may access my NFS share on my Fedora 17?

the root user on the aix system will get mapped to the anonuid/gid
does that uid/gid have permissions to see files on the exported
device?

Have you tried no_root_squash on the export for the linux machine?
that will make root on aix == to root on linux and is mostly used when
the same admin group admins the set of machines and all can be equally
trusted.
