Cool Colin! Thanks! :)
Okey, dosen't sound to hard. Unpack initrd, make a preseed.cfg file in root, config isolinux.cfg, pack initrd, done. :)
But what bootparameter should I use in isolinux.cfg to point to my answerfile in initrd.gz? Thank you for all your help!

We try to keep the initrds as small as possible for a variety of
reasons, and so the netboot initrd doesn't have support for mounting CDs
in general. You could probably plumb it together, but it would be quite
I think your simplest and best option is to use initrd preseeding, which
lets you produce a standalone image which doesn't depend on either a CD
or a network for preseeding. You set this up by installing your preseed
file as "preseed.cfg" at the root of the initrd. This does mean that you
have to unpack and repack the initrd, but that's not too hard. You
unpack by creating a fresh directory, changing into it, and running:
zcat /path/to/initrd.gz | sudo cpio -id
You repack by running this from the same directory:
find . | cpio --quiet -o -H newc | gzip -9c > /path/to/new-initrd.gz
