You don't have to have a /dev/mouse link at all; some would say it is
better not to.  If you do have one, it must be linked to the correct
device, namely /dev/psaux.  If you remove /dev/mouse, simply change anything
that uses it to use /dev/psaux instead.

You certainly should not redefine /dev/ttyS0, which is your first
serial port.

Check the interrupts in use by running `cat /proc/interrupts'.
