Ubuntu Servers :: D-Link DFE-530TX In Karmic 9.10?

(Disclosure: I posted this in the other forums yesterday and realized this is the better place for it. I'll get rid of the other one.) I'm trying to add a second NIC to my Karmic 9.10 (Server Edition) as eth1. The new NIC is a D-Link DFE-530TX+ [URL]... It seems like everything should be working fine because it showed up in ifconfig with no configuration after I put it in my machine and it's even is able to get an IP address from the DHCP server in the router.

The problem is that it's not transmitting anything. I can't SSH into it from my other computers on the LAN, and when I ran a sniffer on the interface it was directly connected to there were no packets.

Here's lspci:
