I think what you want to do is described in Bob Stayton's book here:

In particular:

(I've corrected a typo for Bob there.)  Those attributes are on the
'imagedata' element.  You can supply those attributes for all your
document's images without regard to how large they actually
are---images that are too big are scaled down, and everything else is
left alone.

You will need to replace fo/graphics.xsl with the current version from
CVS---this functionality only works post-1.68.1.
