We've tested a TG789vn router (Aug 2011) which had beta IPv6 firmware (10.1.0.3), and this works. A bit more info here: [1]
Apple Airport Extreme
The Airport Extreme claims to support native IPv6 over PPPoE but we don't know of anyone who has it working. It still works via tunnels though (tunnel configuration explained on the knowledge base. You need to set the remote tunnel endpoint address to 81.187.81.6, and you need two /64 subnets off us. Assign an IP from one /64 as the WAN address and set the default route to our ping address "bottomless", which is 2001:8b0:0:81::51bb:51bb. Set the LAN address to the first usable IP on the second /64 and it should just work.
