There are modems out there that can convert PPPoA from telephone wire into PPPoE on ethernet cable.
See (for example) http://www.draytek.co.uk/products/business/vigor-120 -- read the blurb. Word of warning though (since I have the modem, although not [currently] using it in that mode): The networking stack on it is pretty terrible and it doesn't obey stuff like responding correctly with MTU exceeded errors or forwarding them correctly or something. Don't recall specifics. Not sure if this applies to when you are running it in this special PPPoA-PPPoE bridge mode, since I've not yet tried that. I'm still searching for a decent ADSL modem for my parents' place (terrible wiring, I like to say internet is down 5 minutes every hour)...
