OK, so kbdcontrol(8) depends on the active console driver, be it sc or 
vt, and kbdcontrol(8) searchs for the files in either 
/usr/share/syscons/keymaps or /usr/share/vt/keymaps.

In my case there's virtually no difference between norwegian.iso.kbd 
for sc and no.kbd for vt.

Anyway, I learned something today, and I finally got Norwegian 
keyboard layout in my kernel.
