Why don't you use a post-install script like the following (not tested)?
========================================
#!/bin/sh
# add all your interfaces...
for i in eth0 eth1; do
# configuration file
cfg=/etc/sysconfig/network-scripts/ifcfg-$i
# mac address
hwaddr=`/sbin/ifconfig $i 2>/dev/null | sed -ne "s/.*HWaddr //p"`
# check if HWADDR label is already present in the config file
if grep -q HWADDR $cfg; then
# replace
perl -pi -e "s/HWADDR=.*/HWADDR=$hwaddr/" $cfg
else
# add
echo HWADDR=$hwaddr >> $cfg
fi
done
========================================
