Very interesting.  I added the serverflags section and set option NoAutoAddDevices 
to true.  This did indeed correct the problem.  However, info mice still showed two mice,
with the vmmouse selected.  Then I noticed that my xorg.conf was using
the VMMOUSE module, even though I'm running qemu-kvm.  Changing it to
use Mouse0 and the mouse driver also corrected the problem.
