To answer my own question (not sure if this is good or bad ;-)):

I got the the idea of using "growisofs" for adding (in my case) a
kickstart file and then running "implantisomd5" again.  This seems
to work (I only tested it with KVM with CD-ROM ISO files).  Example:

  growisofs -U -J -R -T -M Fedora-15-x86_64-DVD.iso ks.cfg
  implantisomd5 Fedora-15-x86_64-DVD.iso

This is pretty straightforward and easy.

Are there any caveats in manipulating the ISO image this way?
