I'm not sure that the way you handle making a new device is proper,
because you duplicate functionality from the kernel autoconf routines and
when that evolves, btuart would be left behind..  I think it would be
better to use config_attach_pseudo()/config_detach() to handle that, see
dev/hpc/hpf1275a_tty.c for a nicely written example of that.
