Configuring Two Serial Lines on Cisco 2610

[Augurer]

I'm attempting to enable a second serial line on our Cisco 2610, and am having difficulties allowing both the original T1 and the new T1 to work simultaneously.

I am unsure if the issue is with the configuration of the OpenBSD server, or if it is the router itself.

What do I need to do on the router, other than configuring the interface, to allow both Serial lines to feed the same Ethernet interface?

We currently have a static route of 0.0.0.0 0.0.0.0 Serial0/0 defined.

I am planning on a similar implementation of Dual T1's on Cisco routers and I had a couple questions.
1) We are planning on adding a 2nd T1 to the Internet and our provider will be Cogent for both T1's, however, Verizon provides the local loop for the current T1 and this is under a long contract. When we add the 2nd T1 we COULD get the local loop T1 and Internet T1 BOTH from Cogent. Should bonding of these T1s still work? Cogent mentioned using CEF, but sales said the local Loop may be an issue.
2) For Bonding on Cisco does it have to be on a DUAL interface card or can two T1 DSU/CUS WICs be bonded or should/can I use CEF on the routers? I have an existing Cisco 2610 on the one end, but I may replace that with a newer 2811.

You try ip route-cache command? The no ip route-cache on the serial interfaces turns on process switching, which load balances on a per-packet basis.
