Ok, so I've got Embarq DSL, and they gave me one of those 660 modems and it works okay. What I'm trying to do, is get my Cisco 2610 with a WIC-1ADSL to take care of routing and tranceiving the connection. I've confirmed my configuration multiple times, and still nothing. I finally talked to Embarq, and they said that they showed a physical connection, but my connection wasn't "registering" properly with Redback. Is it possible to configure my Cisco router to work like this? How does Redback work?

They work with PPPoE (always involved when there's redback). So you need to configure your router for PPPoE. If you think you have partially done so already, send here the relevant config you have.

No, that's not pppoe.
One example:

hope this helps, please rate post if it does!

I looked into PPPoE, and it doesn't quite look right. Embarq says I'm not a PPPoE customer, and I set the encoding on the old 660 modem to RFC 1483 and that worked. In talking more with embarq, they seem to be saying that there isn't any "authentication" happening, but that the redback server cross checks the IP address with its own records, and that the connection just isn't getting that far.

Ok, then try that:
interface ATM0/0
description WAN Connection
no ip address
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
no bridge-group 1
no pvc 8/35
int atm 0.1 point-to-point
bridge-group 1
pvc 8/35
encapsulation aal5snap
check with show atm pvc is packets are sent and received on the pvc.

Okay, tried that, and I get the same kinda stuff.
I try: ping 65.41.113.1 source bvi1 and I get nada. Here is my sh int and sh run:
