Funny.  My IPv6 config works like a charm, on both 7.2-STABLE and
8.0-STABLE.  Related config settings look like this:

gif_interfaces="gif0"
gifconfig_gif0="81.187.76.162 81.187.81.6"

ipv6_ifconfig_gif0="2001:08b0:0151:0001::1/64"
ipv6_prefix_de0="2001:08b0:0151:0001"

ipv6_enable="YES"
ipv6_defaultrouter="-interface gif0"
ipv6_default_interface="gif0"
ipv6_gateway_enable="YES"

rtadvd_enable="YES"
rtadvd_interfaces="de0"

This causes my machine to autoconfigure an IPv6 address on the ethernet
i/f, plus provide rtadvd service to anything else wanting IPv6 connectivity
on my home LAN.  IPv6 traffic from the home LAN is routed via the tunnel to
the IPv6 tunnel handler provided by my ISP, but the only reason I need to do
that is because IPv6 aware consumer broadband routers are kind of hard to
obtain.

	Cheers,
