This is (I believe) because GDM now acts as it's own 'user' of
sorts...and likewise has it's own settings for things like power
management, theme, screens, etc (hence forth why your power settings are
not honored when not logged in). See below for possible solution:

I'd imagine setting the power settings for the GDM user (similar to the
way one would currently control the GDM theme under then new system)
would get you what you want. so...
     1. log out (get back to to GDM)
     2. ctrl+alt+F2 to a tty terminal, and log in
     3. enter the following:
             1. export DISPLAY=:0.0
             2. sudo -u gdm gnome-control-center
     4. ctrl+alt+F7 back to the GDM screen...you should not have a
        Control Center window open
     5. Go to the "System > Power Management" area, and open it...you
        should get the familiar gnome-power-manager window, from which
        you can set your settings for the login window.
     6. When you're done, close the Control Center, go back to the tty
        and logout, then test... It should perform as expected.

Hope that helps!
