:Isn't the BIOS on modern computers providing emulation of PS2 for USB

    Some BIOSes do do this, using SMM to emulate the PS2 port.  It has
    always been a bit hokey because the emulation doesn't always mesh
    properly when the kernel tries to switch over to the USB keyboard.
    Personally speaking I would rather not depend on such a feature.

    I am not familiar with NetBSD's autoconf framework but I would hesitate
    to change something so basic in our boot code.  It is already fairly
    fragile as it is and I'd rather not open that can of worms so close to
    the 2.0 release.
