I've added \suppressfontnotfounderror to the source:
    http://github.com/wspr/xetexref

Will update to CTAN sooner or later. (I have trouble doing so from 
behind the proxy at uni.)

I don't know the syntax of \XeTeXpdffile either, so contributions 
accepted. I figure this is one of those primitives that will rarely 
come up since it's well abstracted already by \includegraphics.

Thanks :)

I just add primitives when I notice they're missing. This resulted in a 
couple of primitives being left out of LuaTeX because of omissions of 
mine here...oops.
