Oddly enough, the forgetful NIC does seem to work properly once Fedora
boots up. The issue is that I can't rely on MAC address identification
to allow my router to assign the same address (and forward ports to
it) using DHCP since NetworkManager is picking a random MAC and slowly
incrementing the ethX device every boot. The secondary issue is that
it is making a mess in my /etc/sysconfig/networking/ directory by not
clearing out old entries.

The only indication I get that it is getting cleared is that Windows
reports it as having a MAC of 00:00:00:00:00:00.

I was just wondering if there was another way to address a NIC (PCI
ID?) to be able to assign it a consistent MAC on each boot.

This happened once to one of our many HP dl380's.  Just one.
And it booted with 0's ~70% of the time.  But otherwise worked.

Add to /etc/sysconfig/network-scripts/ifcfg-eth0
MACADDR="1a:2b:3c:4d:5e:6f"

Assuming it's eth0, and substitute your real MAC address.
If the interface can be programmed at runtime, this should do it.
