Strange... in my case loading the module afterwards didn't work either
when burning the image to a CD-RW and using that CD as the physical
medium.  That was back in January 2007.

Both geom_xboxhd and geom_xbox360 check pp->mediasize in their taste
functions right after setting up the GEOM trace, so their behaviour
should be similar.
