Well, not quite. A stable/10 kernel (r292399) configured as below did 
not exhibit a Norwegian keyboard layout when booted in single user 
mode. :-/

kern.vty="vt"

options		UKBD_DFLT_KEYMAP
makeoptions	UKBD_DFLT_KEYMAP=no

options		ATKBD_DFLT_KEYMAP
makeoptions	ATKBD_DFLT_KEYMAP=no

Instead of getting the letters æ ø å when hitting on those keys on a 
USB keyboard, I got the characters ' ; [, in the spirit of US 
keyboards.

Full multi user mode works as expected with

keymap="no"

in /etc/rc.conf.

/usr/obj/usr/src/sys/KERNEL/atkbdmap.h begins with:

/*
 * Automatically generated from /usr/share/vt/keymaps/no.kbd.
 * DO NOT EDIT!
 */
static keymap_t key_map = { 0x6d, {

The same goes for ukbdmap.h in the same directory.

Nothing seems to be wrong with the generated .h files.

Alas, the options and makeoptions for selecting a default keymap does 
not work, at least not for USB keyboards.
