My Thomson Speedtouch (716v5WL) allows it to be set up as an ethernet
bridge, effectively turning into a fancy modem.

Eg, my setup is like this:	   Public IP		  Peer IP
LAN switch/AP ----------- FreeBSD Router------- DSL ST -------- Peer
Effectively, the speedtouch just hands everything off to the bsd router,
which in turn knows nothing about ADSL or PPP, and just uses the
standard em(4) network driver.

None of this stuff was configurable through the speedtouch's web
interface, but is fairly straightforward once you read the 300 page
manual, the 200 page CLI manual and dissect the configuration templates
that tell the box how to operate.
