I think this should work--it has worked on the few tests I have done, but I 
haven't used it for very long.  Let me know if you have any problems.

(defadvice server-goto-line-column (after server-visit-region.tex
  "When visiting a file from an external source, make sure that we
are not narrowed, since the external source almost certainly
uses absolute file line numbers."
  (when (string-match "_region_.tex\\'" (buffer-file-name))
    (save-excursion ;; in case we don't find the other file we at least want 
the right line...
      (if (re-search-backward

nil nil)

                (col (cdr (ad-get-arg 0))))
            (if offset (setq line (+ line (string-to-number offset))))
