Check the installed kernel append line to make sure the rdblacklist option  
is not being pulled from the kickstart boot line.  If it is you can add  
this to the kickstart post install section:

/usr/bin/perl -p -i -e 's/rdblacklist=MODULENAME//' /boot/grub/grub.conf

As I pointed out the script I sent changes all interfaces to DHCP=none.

If you are using it and you don't want it to do that then remove this line:

/usr/bin/perl -p -i -e 's/dhcp/none/'  
/etc/sysconfig/network-scripts/ifcfg-${NETDEV}-tmp
