Did you try adding 'network --device=em1 ...' in your kickstart file?

The feature is called 'Consistent Network Device Naming' and you can 
read more about it here:
http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming

If you don't want any of the interface name changes then you can boot 
with biosdevname=0 and use the old ethX interface names. Optionally 
don't install the biosdevname package.

If you want to change an already installed system back to using ethX 
then I guess you'll have to boot it with biosdevname=0 then delete 
/etc/udev/rules.d/70-persistent-net.rules and fix the filenames in 
/etc/sysconfig/network-scripts/ (mv ifcfg-emX ifcfg-ethX) and fix the 
DEVICE="emX" entry in those ifcfg-emX files. Never tried it so YMMV.

HTH,
Patrick
