Okay, here is a crazy idea.  Maybe one can use hyperref and place \url{}
and/or \href{}{} macros in the org file.  These will turn into clickable
links in the final PDF.  In them place URLs that look like:

  file:///path/to/foo.tex.orglink?line=42

And then use .mailcap (or whatever MIME config that xpdf/evince/etc
honors) to map the .orglink extension to a script that parses the URL
(does that full URL get passed?) and invokes emacs to open foo.tex at
line 42?

If that much can be made to work (big if!) I see one problem in that the
/path/to will break if the source is moved.

Chance of success: 10%

-Brett.
