aha! actually I'm using openbsd 2.9-beta and bind-9.1.1 from port tree.
nslookup is deprecated now.  recently I always use dig.
I suppose nslookup will disappear when openbsd integrates bind9 (-:

anyway, it's true some utilities (e.g., /usr/sbin/{nslookup,dig}, apache)
are not yet ipv6 sensitive.
ipv6 integration into *BSD is still in progress.

======================================================================
  x is OpenBSD IPv6 ready?
      yes. OpenBSD integrates IPv6 implementation of KAME project.

  x how to configure ipv6 network with openbsd

    v link-local
      IPv6 link-local address is attached automatically
      to each network interface.  manual configuration is not necessary.

    v site-local and global
      IPv6 router supply address prefix information;
      non-router node listens to the advertisement from the router and
      configure itself.
      IPv6 router runs rtadvd(8), non-router node runs rtsold(8).

    v tunneling setup
      gif(4) device (generic tunnel interface) provides ipv6-on-ipv4 tunneling
      functionality to connect two isolated ipv6 networks over ipv4
      connectivity.  on OpenBSD ifconfig(8) command is used to setup
      gif tunneling. (note that there's no gifconfig command on OpenBSD.)

    v routing
      OpenBSD distribution consists route6d, RIP6 routing daemon.
      alternatives are zebra and mrtd, included in OpenBSD port tree.
      see also zebra and mrtd for IPv6 multicast routing.

    v naming service issues
      you can mix IPv4 and IPv6 entries in /etc/hosts and /etc/resolv.conf.
      BIND shipped with OpenBSD distribution is based on BIND4, but
      some patches added for IPv6 resource record handling
      (e.g., AAAA records).
      note that not (yet) all userland tools are IPv6 compliant.
