Have you tried adding -P to the mount command?

	(From man mount_nfs)

     -P      Use a reserved socket port number.  This is useful for mounting
             servers that require clients to use a reserved port number on the
             mistaken belief that this makes NFS more secure. (For the rare
             case where the client has a trusted root account but untrustwor-
             thy users and the network cables are in secure areas this does
             help, but for normal desktop clients this does not apply.)

	If this fixes it then you might want to consider sending in a
	send-pr suggesting adding a comment about this to the NOTES
	section to mount_nfs!
