Load the PNG into something which can save out a raster .pdf and  
place that.

ISTR xdv2pdf on Mac OS X can place a .tif (since it uses  
quartzcontext to do the heavy lifting of handling image formats).

If memory serves, you need to specify the default text colour too  
(this is probably why JK was thinking xdv2pdf makes RGB) --- see my e- 
mail to JK for the code which I used on my most recent project.
