You snipped out the relevant part of my response.

<http://pkgs.fedoraproject.org/cgit/gdm.git/tree/gdm.spec#n348>

This is what it says there:

- Require gnome-shell. We no longer use the fallback greeter.
  (Since gdm 3.7.92).

If you look at the spec file, it includes a session file (line 283):

  %{_datadir}/gnome-session/sessions/gdm-shell.session

In my understanding, this means there is no hard dependency.  Of course
the constant CPU load could be a gnome-shell bug, but the gnome-shell
dependency does not look necessary from what I see.

It is very easy to test actually; just rebuild the stock fedora gdm
source rpm without that line (there is one more, but that just includes
an icon) and see if gdm still works normally.

Anyone care to test?
