At first, I thought it was this, but I've already narrowed my .emacs to

(require 'mmm-mode)
(setq mmm-global-mode 'maybe)
(mmm-add-group
 'fancy-html
  '(
   (html-php-embedded
    :submode php-mode
    :face mmm-code-submode-face
    :front "<\\?\\(php\\)?"
    :back "\\?>")
   ))
(add-to-list 'mmm-mode-ext-classes-alist '(html-helper-mode nil fancy-html))

And with such a tiny config, my file is still tagged as modified (at
least with Emacs22, it's OK with Emacs 21). Maybe it's because of
Debian's initialization, but I doubt it.

I tried debugging the wole process, I even learned to use edebug as the plain
backtracing wasn't enough, but I can't find anything for now. I'll try
debugging once again as I can't think of anything better.
