He actually did some up for us way back when. They look the standard
callouts in /usr/share/sgml/docbook/xsl-stylesheets/images/callouts,
with a soft dropshadow on them.
Just in case, I've made some tentative callouts that you can find at
http://www.megacoder.com/callouts/
I don't pretend they're great, or even usable. They are, however, available ;-)
