I think the following should do it.
First: put this line with appropriate numbers/filenames in /etc/named.boot:

primary	XXX.XXX.XXX.in-addr.arpa	XXX.XXX.XXX.db

Second, create /etc/namedb/XXX.XXX.XXX.db (replace X's as needed) with the 
following content:

@	IN	NS	prim-name-server-to-delegate-auth-to.
	IN	NS	sec-name-server-to-delegate-auth-to.

Do not forget to put trailing dot!

Then, restart named. It should work fine then.
Good luck.
