I don't think the SpeedTouch modems support bridging from PPPoA to Ethernet
to the best of my knowledge -- I only know of one very specific model of
D-Link ADSL modem which will do this (DSL-500G+ I think).

You'll probably have more luck using a native ATM card hooked up to the
ATM-25 passthrough port on the SpeedTouch and using userland PPP to get
PPPoA encapsulation through to the BSD box.

We don't support PPPoA in Netgraph [yet], I have a paper design for such
a thing I haven't had any free time to implement.
