Of those adapters, which of them expose themselves as real ATM interfaces, and not as Ethernet bridges to ATM?

A lot of adapters, including the Solos, are a "bridge-on-a-board" type design, which I'm not a big fan of, in part because the dumbed-down abstraction hides from you a lot of the useful instrumentation on the device...

The Solos, for instance, doesn't log to dmesg when it loses sync or gets a bit error, etc.

Ok, this through me for a loop.

If you're using br2684ctl then it creates the device nas0 for you.

But if you're not using it, what is the name of the device that gets passed to pppoatm?

I don't see anything being auto-created.
