I have successfully setup reverse link-lock IPv6 addresses on my campus 
(> 1000 machines) as follows :

   zone "0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa" {
            type master;
            file "revzones6/fe80.head";
            allow-query {
                    via;
                    myself;
            };
    };

and the zone file :

@       IN SOA krishna.via.ecp.fr. root.krishna.via.ecp.fr. (
                2005091522      ; Serial
                1d              ; refresh
                1h              ; retry
                1w              ; expire
                1h )            ; negative response TTL

        IN NS   ns0.via.ecp.fr.
        IN NS   ns1.via.ecp.fr.

8.5.d.3.5.f.e.f.f.f.8.1.0.e.2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa.  
IN PTR     klupfel.ipv6.local.
b.b.6.1.2.0.e.f.f.f.2.0.8.0.2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa.       
IN PTR     helou.ipv6.local.
9.6.6.4.a.f.e.f.f.f.0.6.d.0.2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa.       
IN PTR jamond.ipv6.local.
; etc...

However, we are not using IPv6 for client-to-server DNS queries. It 
works fine with "dig -x". Might be some stupid error such as negative 
DNS cache or typing error.
