I've got an old Dell Optiplex with an integrated Broadcom network device that I've been using for a while. I'm trying to add a second network card, a Linksys LNE100TX, on eth1 and I can't get it to work.

Here's my /etc/udev/rules.d/70-persistent-net.rules:

# PCI device 0x14e4:/sys/devices/pci0000:00/0000:00:1c.4/0000:03:00.0 (tg3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:19:b9:13:d1:b7", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x11ad:/sys/devices/pci0000:00/0000:00:1e.0/0000:04:00.0 (tulip)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:a0:cc:33:53:04", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

And ifconfig -a:

eth0      Link encap:Ethernet  HWaddr 00:19:b9:13:d1:b7  
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::219:b9ff:fe13:d1b7/64 Scope:Link
          RX packets:12871 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8378 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:7258267 (7.2 MB)  TX bytes:1426340 (1.4 MB)

eth1      Link encap:Ethernet  HWaddr 00:a0:cc:33:53:04  
          inet6 addr: fe80::2a0:ccff:fe33:5304/64 Scope:Link
          RX packets:0 errors:12 dropped:0 overruns:0 frame:0
          TX packets:0 errors:24 dropped:0 overruns:0 carrier:24
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

lo        Link encap:Local Loopback  
          inet addr:  Mask:
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:794 errors:0 dropped:0 overruns:0 frame:0
          TX packets:794 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:84950 (84.9 KB)  TX bytes:84950 (84.9 KB)

However, sudo ifup eth1 gives me "Ignoring unknown interface eth1=eth1."

Lights on the card start flashing when I connect it to a router, but network-manager doesn't seem to notice. If I tell network-manager to connect to eth1, it sits and tried for about a minute and then eventually gives up.

Does this look like a driver problem? A simple system misconfiguration somewhere? I'm stumped.
