I took a look at the GDM source and it is hard coded to call metacity.
An easy, patchable[1] workaround is to create a call for xfwm4 (or
whatever other window manager). At one time though, wasn't there generic
support for window managers that was switch-able through /etc? Why is
GDM hard coded like this?
[1] Crude patch is attached.
