Windows formatted iPod's have a fake DOS BPB at the start of their disk.
If you tried to mount it as a msdos filesystem before this change, the
kernel would panic.  Now you get EINVAL.  If you stick GEOM_APPLE in your
kernel, then the apple label at the start of the disk is recognized, and
you can mount /dev/da0s2 as a msdos filesystem.
