Your post tweeked my curiosity, and I couldn't find anything. However, I did run across a few converters that run from the command line that could turn PDFs to JPEGs and such. Would probably be very combersome on multiple-page docs, but if its your only option... what are you going to do?
This one seems to be recommended.
Hope this will help. If you do find a real PDF viewer, please post it. I'd like to see it.
