It seems that description of majors/minors there is absolutely irrelevant to the freebsd device nodes. Devfs simply does not work this way anymore for long time. Moreover, you cannot create special node that would become a node used to access device driver in the freebsd. The only use that is left for mknod c|b is to create special nodes on the filesystems exported by NFS for other un*xes.
