Normally, the nic devices are renamed to match the DEVICE= name specified in the 
/etc/sysconfig/ifcfg-eth? file with the matching HWADDR= mac address even if 
they were detected as something else.  Can you use these and still layer the 
bonding on top of them (they don't have to have an IPADDR)?  Note that they get 
the name of the DEVICE= inside the file, not the eth? of the filename if they 
happen to differ, and it may not work if you don't have matches for every nic.
