USB Keyboard during booting?

Does anybody else have a USB keyboard? And if so does it work during boot? As it so happens I keep two keyboards plugged in, one English (PS2) and one Swedish(USB), so I can always use the ps2 one, for those rare instances I need to do a boot option. Which also leads me to another question while I have your attention. Would it be possible to configure each keyboard for a different input language, rather than switch in software when I switch keyboards. Thanks, Pflodo.
