How about changing the udev rules to reset your interfaces to eth0 and eth1 ?

Typically /etc/udev/rules.d/z25_persistent-net.rules contains lines like :

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="aa:bb:cc:dd:ee:ff", 
NAME="eth0"
When you change hardware, udev will see the new MAC address and 
create rules for the next available interfaces. Just change eth3 to 
eth0 (or whatever the correct arrangement is) and after reboot you'll 
have the same interface names you originally had.
