I just recently ran into this while trying to get NFS mounts over ipv6
(supported in NFSv4).  The NFS server should support exporting to both
v3 and v4 clients.  Now, whether you have to explicitly configure nfsd
to use one or the other, I couldn't tell you off hand.

In any case, it should support either one... and in my experience,
getting a NFS mount using any NFS version is a matter of passing the
parameters to the mount command...

Here's a Red Hat page with info on mounting either NFSv2 or NFSv3
shares via mount:
http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Deployment_Guide-en-US/s1-nfs-client-config-options.html

Here's a Ubuntu man page on mounting nfs v3 and v4 shares:
http://manpages.ubuntu.com/manpages/dapper/man5/nfs.5.html

And here's a Ubuntu help page on configuring NFSv4:
