To my knowledge db2ps is the show-stopper - I only eats
.eps-files.

Try the following - Note line no 2. with magic

<!doctype book PUBLIC "-//OASIS//DTD DocBook V3.1//EN" [
<!ENTITY % magic-entities SYSTEM "magic.sgml">
  %magic-entities;  <!-- This is where we include it -->
<!entity frihedendato SYSTEM "dato.sgml">
<!entity frihedenversion SYSTEM "version.sgml">
<!entity frihedenappendixRevHist SYSTEM "apprevhist.sgml">
]>

I include three files here....


I have a makefile, where I do
        echo '<!ENTITY magic "png">' > magic.sgml
if I output pdf or html

If I do ps-output, then I have
        echo '<!ENTITY magic "eps">' > magic.sgml

Then I use ImageMagick to convert all my png-files to
eps if ps-output

find images/*.png | sed 's/.png//' | sed 's=images/==' | \
xargs -i% /usr/X11R6/bin/convert -antialias images/%.png eps2:bogps/%.eps

Well - It is not that straight-forward, but once you
have the setup of the first makefile, then I works.
You can see a Makefile in
http://cvs.sslug.dk/linuxbog/web/Makefile
