I find it unfortunate that the ability to easily customize your GDM
theme wasn't ported to the new GDM, but one nice thing in theory is
that GDM now uses standard GTK+ themes instead of it's own specialized
themes. In order to change  the theme, you change the GTK+ theme (or
in your case, background) for the gdm user. You should be able to do
that by launching gnome-appearance-properties as the gdm user with:

gksudo -u gdm dbus-launch gnome-appearance-properties
