You don't need to setup two servers.  You can simply create two reverse
zones for each of those networks.  Something like this (I just did a
quick copy paste, so most of this will not apply to you, be warned!)

zone "0.168.192.in-addr.arpa" in {
        type master;
        file "db.192.168.0";
        allow-query { 192.168.0.1/16; };
};

followed by...

zone "1.168.192.in-addr.arpa" in {
        type master;
        file "db.192.168.1";
        allow-query { 192.168.0.1/16; };
};

Of course, replace db.192.168.x with whatever you named your files. 

Also look at
http://www.freebsd.org/cgi/man.cgi?query=named.conf&apropos=0&sektion=0&
manpath=FreeBSD+4.8-RELEASE&format=html#ADDRESS+MATCH for more on
"allow-query"

Hope this helps you,
