My knowledge about ATM is minimal. So, I don't realy know how to answer to your question about bridging being transparent to the ISP. But I can tell you for sure that ISPs do not bother if you cannot connect using FreeBSD and PPPoE. You are mainly on your own. I assume that if you use the same settings your modem uses to do PPPoE it won't make a difference to the ISP end. You said you had wrong encapsulation type.
