I don't know what the problem is, but I have some ideas for getting more 

1) Are both cards identical? I understand that using identical cards is 
a bad thing and you might have more luck with different cards. Try 
pulling out one of the cards and see what happens.

2) Go to System > Administration > Device Manager and try to locate the 
cards. Select a card and click on the Advanced tab. The net.interface 
line tells you if it's eth0 or whatever. The objective of this exercise 
is to know which card is eth0, etc.

It might well be that the new kernel decided to call the cards eth1 and 
eth2 so there is no eth0. I've had this happen before. So, the first 
step is for you to tell us what cards you have (both cards) and which 
one is eth0 and which is eth1.

3) Please post the contents of /etc/network/interfaces here.

4) Please use to post the output from lspci and lsmod. 
Include the links on your email.
