This is not quite complete.  And actually, we make a custom boot cd, 
with multiple targets that contain the common parameters, so all 
that's needed at the boot prompt is target, ip and gateway.  You'll 
probably need at least this:

boot: linux ks=http://url_of_kickstart_file ip=... gateway=... 
netmask=... dns=...
