From what I've read, PS/2 is not meant to be hot-swapped. Certain OSes will
crash if you pull a PS/2 mouse out.

I haven't had any trouble with hot-swapping USB mice though. Perhaps switch to
a virtual terminal and back.

I've also found that mechanical switch boxes can lock up PS/2 mice.  Maybe OK 
if you change the switch position before powering on, but not when the PC is 
running.  At one stage the latter caused my mobo to not recognize any device 
on the PS/2 ports until I reset the CMOS to defaults.

Looks like the simplest solution is to buy plenty of mice.
