Ok, rfc1483 obsoleted by rfc2684. Still, the point holds - in xDSL
services every imaginable encapsulation is used and usefull driver
should provide netgraph hooks for constructing arbitrary upper layers.

Especially nice would be autodetection of active ATM VC's,
used encapsualtions and connecting appropriate netgraph hooks
automagically.
