Perhaps I've been working with PostScript too long, but my favourite
method would be:

ps2epsi the original file.

Follow the instructions at the bottom of
http://www.sunsite.ubc.ca/Resources/Graphics/import/merging.html
(starting "The Template File Itself")

using it to embed a single EPS file, preceding it with

595 0 translate % for portrait A4 paper, 595 pt = 21cm
-1 1 scale

The solution is practically guaranteed to work with any postscript
file, no matter what weirdness goes on inside.  If you need any more
pointers, just ask :)

HTH,

Bernard.
