I believe you can edit /etc/udev/rules.d/70-persistent-net.rules and add
lines such as:

# Broadcom Corporation NetXtreme BCM5754 Gigabit Ethernet PCI Express
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="00:1d:09:29:34:03", ATTR{type}=="1", NAME="eth0"

# PCI device 0x8086:0x1079 (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="00:1b:21:08:0d:1c", ATTR{type}=="1", KERNEL=="eth*", 
NAME="eth1"

# PCI device 0x8086:0x1079 (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="00:1b:21:08:0d:1d", ATTR{type}=="1", KERNEL=="eth*", 
NAME="eth2"

Each rule must be on a separate line, blank lines and those starting
with "#" are ignored.

After a reboot, this should cause the NIC with the MAC address
00:1d:09:29:34:03 to be named "eth0", the one with MAC address
00:1b:21:08:0d:1c to be named "eth1" and so on. There are other
attributes you can specify. I use this on F19 and F20.
