/*
* It is not obviously an ADB/PC keyboard. Could be USB,

* This is not enough, we have a few more problems:
*
* (1) The stupid Macintosh firmware uses a
* `psuedo-hid' (no typo) or `pseudo-hid',
* which apparently merges all keyboards
* input into a single input stream.
* Because of this, we can't actually
* determine which controller or keyboard
* is really the console keyboard!
*
* (2) Even if we could, the keyboard can be USB,
* and this requires a lot of the kernel to
* be running in order for it to work.
*
* (3) If the keyboard is behind isa, we don't have enough
* kernel setup to use it yet, so punt to the ofroutines.
*
* So, what we do is this:
*
* (1) First check for OpenFirmware implementation
* that will not let us distinguish between
* USB and ADB. In that situation, try attaching
* anything as we can, and hope things get better
* at autoconfiguration time.
*
* (2) Assume the keyboard is USB.
* Tell the ukbd driver that it is the console.
* At autoconfiguration time, it will attach the
* first USB keyboard instance as the console
* keyboard.
*
* (3) Until then, so that we have _something_, we
* use the OpenFirmware I/O facilities to read
* the keyboard.
