A second serial port would certainly eliminate the last interrupt level
available for the bus mouse (BTW I took the above table directly out
of the Microsoft Mouse User's Guide).  As for configurations that
would require both a mouse and two serial ports, try a CADD system
with a serial plotter and a serial field data collector interface 
(ala Engineers and Land Surveyors). YARTBAT (Yet Another Reason To
Buy an AT :-)).
