Attached are my scripts that I've used.  They weren't written for public 
consumption, so there is no documentation to go along with it.  I think 
if you stare at it you will understand, otherwise ask...

The updates/ directory just contains RPMs that are merged in the 
existing repo on the DVD.  The nec_mangle just replaces files in 
isolinux/ to give me the boot options I want to launch the correct 
kickstart.  The ks/ directory just holds the kickstarts I use.  I also 
insert a modified comps.xml to get custom package groups.  The pkgorder 
script included was necessary as the stock one I had with SL5 didn't 
behave properly; I don't recall what was wrong.
