** FACILITY:
**
** Driver for keyboard and display for PC-style console device.
**
** ABSTRACT:
**
** The driver has been cleaned up a little as part of the StrongARM
** porting work. The main modifications have been to change the
** driver to use the bus_space_ macros, re-organise the sget and sput
** mechanisms and utilise a more robust set of i8042 keybord controller
** routines which are now external to this module and also used by the
** pms mouse driver.

**
** FORMAL PARAMETERS:
**
** dev - device identifier consisting of major and minor numbers.
** offset - offset into video memory
* nprot - unused
**
** IMPLICIT INPUTS:
**
** 0xa0000 - Base address of screeen buffer
**
** IMPLICIT OUTPUTS:
**
** none.
**
** FUNCTION VALUE:
**
** The page that the offset into video memory is located at
** -1 Couldn't map offset
