You're almost there.

But all these commands do is change the MAC address on an existing 
interface,
ie. the interface which the system 'thinks' is eth0
They can't flip the interfaces over. What is eth0 remains  eth0

I bet you Kudzu is changing the adapters. Kudzu authors file includes 
Auld nick himself.

The fix is to

a) find out what are the MAC addresses of each physical interface.
    ie. boot it up, and use ifconfig eth0 when you've figured out which 
is eth0.  Or maybe just open the lid and look at the labels.

b) Change the /etc/sysconfig/network-scripts/ifcfg-eth*
    files to be tagged with the MAC address, eg 
ifcfg-eth-id-00:0B:CD:4E:31:C1

SuSE YAST2 does this for you - sorry can't think that hard about RHEL 
today as I have my SuSE head on. So if above isn't exactly RHEL syntax 
then I apologise.
I'm deep in 'hw ether' type tagging of a system in Edinburgh today, so 
this is on my mind.
