Why are we talking about cluttering up auto-mode-alist with odd filenames?
There files are generated, so it's easy to add to them a cookie like:

  ;; -*- mode: emacs-lisp-data -*-

Actually ~/.emacs.d/tramp already has ;; -*- emacs-lisp -*-
But no other files.  We need to add the same cookie to

~/.emacs.d/places       - Emacs Lisp data
~/.emacs.d/recentf      - Emacs Lisp data
~/.emacs.d/eudc-options - Emacs Lisp code

and to all other files in ~/.emacs.d/
