You could sort that out with udev rules on each machine. Look in the directory /etc/udev/rules.d for the file NN-net_persistent_names.rules you'll need a script which looks for the HWaddr (MAC) address matching the 10gig cards and edit the SUBSYSTEM line for that interface. As you say it should not matter - but I would get them all consistent anyway.
