It appears that the keyboard comes up returning AT-style scancodes, but
the i8042 is configured to convert them to the old XT codes.  Don't ask
me to justify why it was designed this way.

I thought it would be an interesting experiment to always select table 1
(XT codes), and turn off the translation, so that's what I've done.
This may make XT keyboards work, but I neither know nor particularly
care whether that's the case.

If you have any problems with the current pccons.c, please email me.
