I just put in a new motherboard so I'm new to having two onboard NICs...

Several different programs call eth1 for some reason, though I've only got eth0 plugged in and working. For instance, attempting to start my mythbackend fails trying to call eth1, which is strange:
Code:
bean ~ # /etc/init.d/mythbackend start
 * Caching service dependencies ...                                         [ ok ]
 * Starting eth1
 *   Bringing up eth1
 *     Configuration not set for eth1 - assuming dhcp
 *     dhcp
 *       eth1 does not exist                                                [ !! ]
 * ERROR:  Problem starting needed services.
 *         "mythbackend" was not started.
bean ~ # ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:16:E6:4A:3F:E8
          inet addr:192.168.10.3  Bcast:192.168.10.255  Mask:255.255.255.0
          inet6 addr: fe80::216:e6ff:fe4a:3fe8/64 Scope:Link
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:583509 errors:0 dropped:0 overruns:0 frame:0
          TX packets:361219 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:799725536 (762.6 Mb)  TX bytes:28178185 (26.8 Mb)
          Interrupt:217 Base address:0x2000

bean ~ # ifconfig eth1
eth1: error fetching interface information: Device not found
bean ~ # ls -l /etc/init.d/net*
lrwxrwxrwx  1 root root     6 Aug 13 07:35 /etc/init.d/net.eth0 -> net.lo
lrwxrwxrwx  1 root root     8 Aug 13 12:11 /etc/init.d/net.eth1 -> net.eth0
-rwxr-xr-x  1 root root 24317 Feb  8  2006 /etc/init.d/net.lo
-rwxr-xr-x  1 root root  3055 Feb  8  2006 /etc/init.d/netmount
I can't remember right now which other programs have called eth1, but as I get the error messages again I'll post them.

I sifted through some other threads about eth0 and eth1, but nothing looked quite like what I'm getting-- I really just don't understand how these NICs are polled and why... ? Help?

* eth1 does not exist [ !! ]

means that the interface eth1 has not been initialized by the kernel. You are probably missing support for your ethernet adapter. Dual ethernet motherboards often have two different ethernet controllers (perhaps one of them is at 1000baseT, and the other is at 100). Find out what driver your other ethernet adapter uses, and recompile your kernel (or use a module).
