I would think it would work like Fedora 12+; load a F12/13/14 up and start looking. For that matter, CentOS 5 also, as HWADDR has been supported for a long time (in the ifcfg-ethX files in /etc/sysconfig/network-scripts).
Using a recursive grep for eth0 in /etc on my F14 laptop, I find:
udev/rules.d/70-persistent-net.rules:SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:15:c5:aa:bb:cc", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
So it looks like udev is doing these assignments, and by MAC address rather than bus enumeration (a mixed blessing!).
I also see:
sysconfig/network-scripts/ifcfg-eth0:DEVICE="eth0"
so that mechanism is still there.
