All:

I opened up the Acrobat 6 Help files and searched for all mention of
PPD files.

Page 76 of the Acrobat 6 Help file specifically discourages use of other
PPD files to produce PDF:

?       Color and custom page sizes are available if you use the 
        PPD file that comes with Acrobat Distiller 6.0. Choosing a 
        PPD from some other printer may result in PDF documents that
        do not contain appropriate color, font, or page size information. 

All other references to PPD files in the Help file relate to their use in
PRINTING FROM ACROBAT, not for generation of PostScript from applications 
for subsequent distillation into PDF files.

My recommendations are fully consistent with all documentation from Adobe
and still stand!

        - Dov
