* PNPBIOS attachment for the PC Keyboard Controller driver.

*
|
|
* This is a little wonky. The keyboard controller actually
|
|
* has 2 PNPBIOS nodes: one for the controller and the keyboard
|
|
* interrupt, and one for the aux port (mouse) interrupt.
|
|
*
|
|
* For this reason, we actually attach *two* instances of this
|
|
* driver. After both of them have been found, then we attach
|
|
* sub-devices.
