    279  1.1.10.1  bouyer 	 *	    be running in order for it to work.
    280  1.1.10.1  bouyer 	 *

    283  1.1.10.1  bouyer 	 *
    284  1.1.10.1  bouyer 	 * So, what we do is this:
    285  1.1.10.1  bouyer 	 *
    286  1.1.10.1  bouyer 	 *	(1) First check for OpenFirmware implementation
    287  1.1.10.1  bouyer 	 *	    that will not let us distinguish between
    288  1.1.10.1  bouyer 	 *	    USB and ADB. In that situation, try attaching
    289  1.1.10.1  bouyer 	 *	    anything as we can, and hope things get better
    290  1.1.10.1  bouyer 	 *	    at autoconfiguration time.
    291  1.1.10.1  bouyer 	 *
    292  1.1.10.1  bouyer 	 *	(2) Assume the keyboard is USB.
    293  1.1.10.1  bouyer 	 *	    Tell the ukbd driver that it is the console.
    294  1.1.10.1  bouyer 	 *	    At autoconfiguration time, it will attach the
    295  1.1.10.1  bouyer 	 *	    first USB keyboard instance as the console
    296  1.1.10.1  bouyer 	 *	    keyboard.
    297  1.1.10.1  bouyer 	 *
    298  1.1.10.1  bouyer 	 *	(3) Until then, so that we have _something_, we
    299  1.1.10.1  bouyer 	 *	    use the OpenFirmware I/O facilities to read
    300  1.1.10.1  bouyer 	 *	    the keyboard.
