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
                                          (line-col)
                                          activate)
  "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
           "\message{ !name(\\([^)]+\\))\\(?: !offset(\\([-0-9]+\\))\\)?\\s *}" 
nil nil)
          (let ((file-name (match-string 1))
                (offset (match-string 2))
                (line (car (ad-get-arg 0)))
                (col (cdr (ad-get-arg 0))))
            (if offset (setq line (+ line (string-to-number offset))))
            (find-file file-name nil)
            ;; Ironic, but I think cleaner then reimplementing...
            (server-goto-line-column (cons line col))
            (message "Moved from _region_.tex to line %s of %s." line 
file-name))

        ;; else
        (message "This is _region_.tex, but I couldn't find the original 
file!")))))
