Those modules are the old server that doesn't support NFSv4. You can set
the following in /etc/rc.conf:
nfs_server_enable=3D"YES"
nfsv4_server_enable=3D"YES"

or if you want to load the module yourself, do a:
# kldload nfsd.ko     <-- it will load any others that are needed

You'll also need a "V4:" line in your /etc/exports.

Look at "man nfsv4" for more info, rick
ps: The diskless root fs needs to use nfsv3, but other mounts can
    be NFSv4.
