You would only need to use ppp over atm if the unit terminating the PPP connection
(modem or linux box) was directly connected to the transact ATM connection.

In your second "proposed" configuration, if the "modem" is a marconi device
performing PPP <-> ATM bridging, then you would be connecting the modem to the
linux box and using PPP over Ethernet, which is just standard pppd.  If the
modem is some other device capable of PPP and routing, then you would be
internally configuring PPP over ATM on that modem to dial your connection and
then generally using it as the gateway for your network.
