Is it possible to bind more than 1 ip address to the built in ethernet interfaces on a 2621 router?

Yes, you can use secondary addresses for this.
ip address
then for the secondary do this in the interface configuration mode
ip address
Ensure you put secondary after the ip or it will overwrite the primary address.
Hope this helps,

Add this statement to your access-list 1
Router(config)#access-list 1 permit 192.168.1.0 0.0.0.255
Since you are not able to resolve DNS names for the workstations in the 192.168.1.0 network, you will need to configure DNS server setting for the workstations. (you can use the same DNS server as you use for the 10.0.0.0 network)

I got the second IP address (192.168.1.2) bound to the interface of my router, but nothing on that subnet can get out to the outside world. I tried to ping out from a pc with 192.168.1.3, but all I get is unknown host when using names (cisco.com) and request timed out when using ip addresses. I can ping out to places just fine on machines that are on the 10.0.0.0 net work . What else do I need to do? My router config is as follows, but I did go thru and sanatize it change the names to protect the innocent:
