Final comment. I had another look at the files Hannes attached.

To sum it up: You can already see, that these two files were created by the same version of Xpdf/pdftops, but they have defined  differently their "DocumentMedia" and "BoundingBox" statements. FreeBSD is for A4, while Kubuntu is for Letter. Look more closely: FreeBSD is in "portrait" mode (higher than wide), Kubuntu is in landscape (wider than high). Let's look if there are more differences:

kurt soprano:~> sdiff -sbB print_freebsd.ps print_kubuntu.ps

  %%DocumentMedia: plain 595 842 0 () ()  | %%DocumentMedia: plain 793 612 0 () ()
  %%BoundingBox: 0 0 595 842              | %%BoundingBox: 0 0 793 612
  595 842 false pdfSetup                  | 793 612 true pdfSetup
  36.1427 0 translate                     | 36.1427 7.16094e-15 translate

Yes! The difference between "true" and "false" for the pdfSetup is not as important as it seems. But the order of the page size parameters is! It makes Kubuntu change from portrait media orientation to landscape.

----> change the order of the pdfSetup parameters to "793 612" and gs will 
      display it alright (the "true" vs. "false" statement doesn't influence 
      this; a "clean" file will have all the other statements correct as 
      well).

One more thing: 
---------------
I used plain "gs" to look at the files. Later, I also used "gv" and "kghostview". "gv" displays even the faulty Kubuntu file correctly!! kghostview behaves like gs.

Moral:
------
  --> Find out about faulty PS files (rotation, BoundingBoxes): use "gs".
  --> Look at full file nevertheless (and change media size etc.): use "gv".
