        I cheat the other way by letting the nameserver see the
        AAAA's for the root servers that have IPv6 addresses.

        e.g. 
        zone "f.root-servers.net" {
                type master;
                file "master/f.root-servers.net";
                notify no;
                allow-query { localhost; };
        };

        master/f.root-servers.net:
        @ 3600 IN SOA drugs.dv.isc.org. marka.isc.org. 1 3600 1200 604800 3600
        @ 3600 IN NS drugs.dv.isc.org.
        @ 3600 IN A 192.5.5.241
        @ 3600 IN AAAA 2001:500::1035

        The question is what do we wish to test.  A IPv6 only world
        or a IPv6 only network with access to proxies etc. to allow
        access to IPv4 resources indirectly.
