I've missed a couple of updates... the last notice I received on my
kde desktop showed 200+... yikes.

dmesg | grep -i eth

  [1178198.100780] device eth1 entered promiscuous mode
  [1188657.808177] device eth1 left promiscuous mode

Those were the only hits, so apparently eth0 is not being seen at all.

The machine does have two nics and looking again at ifconfig -a  it
shows different MAC and interrupt for each:

eth0      Link encap:Ethernet  HWaddr 00:40:f4:b5:29:41  
          inet addr:192.168.1.54  Bcast:192.168.1.255  Mask:255.255.255.0
          BROADCAST MULTICAST  MTU:1500  Metric:1
          [...]
          Interrupt:19 Base address:0x6f00

eth1      Link encap:Ethernet  HWaddr 00:11:09:ee:6c:04  
          inet addr:192.168.1.42  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::211:9ff:feee:6c04/64 Scope:Link
