Works here in that I get pictures included in the output (yay!),
except of course you need to make this change to libfo-compat.xsl:

A couple of things seem wrong though:

* Transparency seems to come out as black though -- is that something
  that's easy to fix?

* My captions seem to disappear, perhaps underneath the image.  I'm
  using DocBook XML like this:

    <figure id="fig-scale">
      <title>Scale image using <application>The GIMP</application></title>
      <mediaobject>
        <imageobject>
          <imagedata fileref="figs/photos-scale-en.png" format="PNG"
		     contentwidth="3in" contentdepth="4in"/>
        </imageobject>
      </mediaobject>
    </figure>

  I can see the caption in the XSL-FO, but not in the resulting PDF.
  Known issue with external-graphic placement?

Tim.
