Searching Emacs for files that set revert-buffer-function brings up
the following list:

  apropos.el
  bookmark.el
  bs.el
  calendar/todo-mode.el
  chistory.el
  cus-theme.el
  dired.el
  emacs-backtrace.el
  emacs-ert.el
  emacs-package.el
  emacs-tabulated-list.el
  emacs-timer-list.el
  epa.el
  facemenu.el
  find-dired.el
  find-lisp.el
  forms.el
  help-mode.el
  hexl.el
  ibuffer.el
  info.el
  locate.el
  mail/mspools.el
  mail/rmail.el
  mail/rmailsum.el
  mh-e/mh-folder.el
  net/net-utils.el
  net/secrets.el
  net/telnet.el
  proced.el
  progmodes/compile.el
  progmodes/ebrowse.el
  progmodes/sql.el
  replace.el
  simple.el
  tar-mode.el
  time.el
  vc/diff.el
  vc/pcvs.el
  vc/vc-dir.el
  vc/vc.el
  wdired.el

I think this gives a good idea about what modes have revert actions,
but if details are needed, one can look inside these files and see.
