OpenOffice has a PDF export, as well as HTML export.
Aye, but OpenOffice's PowerPoint import is very bad. Subtle differences in font sizes and handling of graphics causes it to severely mess up anything more complicated than simple text bullets.

Free platforms aside, to export PPT to PostScript the best method I found was to use the Adobe PostScript print driver (free-as-in-beer download from Adobe's website). It's default PPD file outputs monochrome PostScript, so you need to patch it as follows:
*LanguageLevel: "2" *ColorDevice: True *DefaultColorSpace: RGB
In Windows, define a printer that uses the Adove driver with the patched PPD and do a Print to File from PowerPoint. Examples of output, after application of ps2pdf:

(the slowly-rendered equations are TeXPoint bitmaps).
All other alternatives I tried, Acrobat not included, produce either broken PostScript (MS driver) or nastily distorted colors (other PPDs) or mis-rendered slides (OpenOffice).
