The new PDF interpreter will not run PostScript, at all.

While it will be possible to drive it from the PostScript environment, it 
directly calls the graphics library, it doesn't execute the PostScript

I'm afraid I don't see a solution, other than turning the PDF file into a 
PostScript file using ps2write, and then executing the PostScript file to 
the PDF device (assuming you want a PDF file back out again).
