Touchpad

[Jim Gettys]

Andres has managed to get it working here; exactly what incantations are
required, I'm not sure.

Zephaniah Hull (who has been working on this), is currently quite sick,
so progress on that end on hold pending him feeling better.

Andres, what did you end up having to do?

You certainly need a Bios upgrade: the symptoms you describe are those
we had here until the right registers were set for the PS/2 port.
