IPv6 over IPv4 over PPPoE?

Has anyone successfully connected to freenet6 when connected to the
internet via PPPoE? I'm connected to my ISP using Nortel's 1meg modem
technology.
Here's the steps I do on my Linux 2.2.15 box. I can ping myself, but
nobody else. I'm sure the MTU sizes are all screwed, but an ICMP packet
should not be affected by that.
