There is existing art in this area: 

 - the much hated SVR4 mechanisms don't fit into our kernel build frame work

but both

 - the FreeBSD 3.0 autoconfig /dev filesystem (the driver declares a 
   dev-filesystem description strucuture with some magic macro, numbers
   are assigned at autoconfig time

 - the BSDI preprocessor approach generating the concrete config.c with
   a special tool assigning all the numbers at kernel config time

should be easy to integrate into NetBSD.
