Which is why I proposed changing these sentences to the past tense,
i.e.:

	The major device number is an integer number which tells the
	kernel which device driver entry point to use.

should become:

	The major device number is an integer number which used to tell
	the kernel which device driver entry point to use.

and:

	The minor device number tells the kernel which subunit the node
	corresponds to on the device; for example,

should become:

	The minor device number used to tell the kernel which subunit
	the node corresponds to on the device; for example,

Because there are also various discrepancies between how FreeBSD and
not-FreeBSD divide dev_t's into major and minor numbers, I would almost
suggest merging mknod(8)'s major and minor argument into one, namely a
(hexa)decimal 32-bit value.
