Can you confirm that the slices are created if you first plug in the
xbox harddisk and kldload the module afterwards?  I once wrote a GEOM
module to slice xbox360 media (kern/107707), which only works if you
first kldload it and _then_ plug in the media.  This is caused by
pp->mediasize == 0 in the taste function.

Note that you'll need a physical harddisk for the test because the
behaviour is always correct when using md images.  I suspect that the
bug is near /sys/cam/scsi/scsi_da.c

Thanks,
Rene
