After discussing the problem briefly with Richard, I have a suggested patch
for org-mobile.el.

This will force checksums.dat to always be Unix line encoding.

--- a/lisp/org-mobile.el
+++ b/lisp/org-mobile.el
@@ -409,6 +409,7 @@ The table of checksums is written to the file
mobile-checksums."
     (files org-mobile-checksum-files)
     entry file sum)
     (with-temp-file sumfile
+      (set-buffer-file-coding-system 'undecided-unix nil)
       (while (setq entry (pop files))
     (setq file (car entry) sum (cdr entry))
     (insert (format "%s  %s\n" sum file))))))

He said he may update MobileOrg to handle other linefeed encodings, but for
the meantime this seems to work for me.
