RTFM http://www.debian.org/releases/stable/i386/apbs03.html.en

  An alternative method is to do a manual installation and then, after
  rebooting, use the debconf-get-selections from the debconf-utils package
  to dump both the debconf database and the installer's cdebconf database
  to a single file:

  $ debconf-get-selections --installer > file
  $ debconf-get-selections >> file

  However, a file generated in this manner will have some items that
  should not be preseeded, and the example file is a better starting place
  for most users.

When I needed to mess with kickstart a while ago I had to spend a number
of troubleshooting cycles just to get the right list of packages to add.
There's a nice place you can list them. But the installer will not
resolve dependencies :-(

Furthermore, I couldn't figure out a way to just ass an extra yum source
and also get packages from there. As a result we had to do that in a
post-install script. At the moment we have a very complex logic in a
post install script.

With preseed I just feed it an extra packages source, the list of
packages I really want, and that's all.
