While I'm not 100% sure, I think you may be able to accomplish this
via boot parameters
'man bootparam' shows that ethernet devices can be assigned based
upon IO and IRQ:
ether=irq,iobase[,param_1[,...param_8]],name
ether=0,0,eth1
This would, of course, require you to know the io address and the
interrupt but it sounds doable.
If you decide to go this route I'd be curious to hear how it works.
On newer hardware it doesn't work at all, in modern hardware (after
the mid-90s), the BIOS assigns the IO and IRQ at boot time, so you
can't reliably predict what it will be in order to pass it on the
command line. Also the arguments to ether= can vary depending on the
driver being used for the card.
On top of all that, ether= has been deprecated as of kernel 2.6.10.
You can change the device name at run time though, with ip:
ip link set eth0 name eth1
but putting HWADDR in network-scripts/ifcfg-* does this for you, and
you don't have to figure out which ones are wrong in order to change
them.
Cheers,
Harry

Hello,
I had a query from a customer who has four network interfaces in
his server and while doing a kickstart, he want interfaces with
particular MAC addresses get assigned the name eth0, eth1 etc..
ie.. He wants the interface with MAC '00:14:5E:B3:56:F4' be eth0,
interface with MAC '00:14:5E:A7:0B:B8' be eth1 and so on..
I was only able to locate the directives for the 'network'
section in kickstart, specified below. Are there any directives
available to configure MAC addresses or is there a work around
for this.
The only way to do configuration that kickstart can't do directly,
is to write the configuration files yourself from a %post script
%post
cat <<END > /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR= 00:14:5E:B3:56:F4
IPADDR=192.168.0.1
NETMASK=255.255.255.0
ONBOOT=yes
END
cat <<END > /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth0
BOOTPROTO=static
HWADDR= 00:14:5E:A7:0B:B8
IPADDR=192.168.1.1
NETMASK=255.255.255.0
ONBOOT=yes
END
