This is what we do on leased line customers (or ATM point-to-point PVC DSL 
access).

This is what we do for "bulk" DSL access, which is presented to us as
L2TP connections, so RADIUS is the "natural" way to do it.

Yes, there must have been some misunderstanding.

Option 2) is something we can't easily test, as we only have a handful
of DSL lines with bridged ethernet available, and on those, our equipment
can't do IPv6 RBE (Cisco 12.3, not 12.3T).  Doing it with a bridge-group
might work, but definitely doesn't scale.
