There has been some confusion a while back, I don't remember the details.
As for debugging:
1) What do you have in rc.conf? ipv6_enable should be set to "YES" and
ipv6_network_interfaces should be "auto" or a list of the interfaces that
should use IPv6.
2) rtsol(8) is used to initiate stateless autoconfiguration. You might
want to try "rtsol -d interface".
3) Check the net.inet6.ip6.accept_rtadv sysctl. ipv6_enable should take
care of this.
4) Check your firewall rules.
