Basically you need to put the ethernet MAC address of the new card in
the HWADDR= line of the appropriate ifcfg-eth? file. Assuming you are
talking about Centos 5.x, the devices are renamed to match these files
based on the hwaddr entries even if they were detected in a different
order. But some conditions that I don't understand may trigger all of
these files to be renamed with a .bak extension at bootup and new
default dhcp configs created instead. This is never fun when your only
access to the machine is through the network.
