Nope, far far less complicated than that.

Almost universally DSL modems can be configured as either a NAT gateway
or Ethernet <-> ATM bridge - I say "almost" to leave open the
possibility that there exists a device that can't go either way; I've
never seen or heard of a device that can't.

The default configuration for QWest DSL is for the DSL modem to be a NAT
gateway. Qwest will configure the DSL modem for bridge mode if you ask
them, but you need to know to ask them ;)

If Qwest provided the DSL modem they have the necessary information to
change it's mode on their support web site.

IIRC there are a number of IPv6 over IPv4 tunnel mechanisms available.
One of those will be your best bet.
