here's an implementation of this...

there's one change to main.c, adding gsm_gsd_start() before showing the
splash screen.

it seems to work well.

two other changes that would need to be made:

        1.  remove gnome-settings-daemon from default.session
        2.  remove gnome-session stuff from g-s-d

how's this look?
