I trust you, but on my multi-nic systems, I found a better solution :)
As I use Xen to virtualize my systems and as I don't want to have multiple 
network cables running side-by-side, I started using VLANs.

I know have all the NICs names eth1,eth2,...ethn.
I throw them all as a bonded network device: bond0 (the other ends go into a 
switch supporting bonding network ports)
then on top of that, I have VLANs with distinctive names (lan, dmz, guest, 
vm,...) and link these as required to different Xen-domains.

When the network names get renamed suddenly to the "non-predictive" scheme, my 
system refuses to boot.
Before that, I would use mac-addresses to link ethx devices to names that make 
sense to me. (see above for the names)
