Guten Tag, tech@.

I'm having some ordinary ps/2 (minidin) keyboards.
> pckbd0 at pckbc0 (kbd slot)
If I'm plug in any of such keyboard to PC, after OS (OpenBSD 4.2)
booted, I see message
> pckbcintr: no dev for slot 1

I can't understand why its talking about "slot 1" (PCKBC_AUX_SLOT).
Kernel with next diff (setting slot = PCKBC_KBD_SLOT for testing)
allow me make "hot swap" of keyboard(s). I think what slot detection
doing something wrong, but I have no idea, what stat and 0x20 stand for.

So, what can we do with this?
