This is a brand new machine that has only the one OS installed. I
tried booting Knoppix and it wouldn't boot. So I don't think we're
going to see other OS results.
After observing that /dev/input/mice was responding to the mouse I
changed the X config to
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Buttons" "7"
Option "Resolution" "1000"
EndSection
and restarted X and at that point it started working. This is the
first time I've seen the ps/2 mouse work with /dev/input/mice.
This is basically the same X configuration that wasn't working when
the system first installed.
