Well, the issue was that the DSL service /was/ working fine. Even during 
the outage, I could run:

# pppoe -I eth1 -A

and get a reponse from hardware at wellington st - so the link layer was 
working, as was the ethernet-over-ATM stuff. However, a connection 
attempt resulted in a message from the server:

PADS: System-Error: No more sessions allowed for this host

In hindsight, Andrew Howell's comments that the host's MAC address was 
being blacklisted seem to be the most likely answer. As the modem, in 
bridged mode, is exactly that, the PPPoE server would see the host's MAC 
when the PPPoE session started. If you use the router, the client has a 
different MAC address, so it works.

I wish I'd thought of changing the MAC address of the NIC at the time.
