well, after some more experimentation, it sees to be a FreeBSD client issue.
if the client is linux there is no problem.

BTW, I 'think' I'm using the experimental server, but how can I be sure?
I have the -e set for both nfs_server and mountd, I don't have option NFSD,
but the nfsd.ko gets loaded.
