Set bit 0x8000 in the psm device by modifying your loader.conf:

psm_flags=0x8000

This will force a mouse reset when switching with the kvm box.

This should be installed as the default mode and not called a "hack"
since it is the most logical thing to do.  Unfortunately, the maintainer
of psm.c has some sort of reservations about making this behavior the
default.  My wireless mouse requires this setting with no intervening
switch box.  I never see multiple instances of reset behavior, so I
don't know why this completely logical code path is relegated to the
euphemism of "hack" and not made default.
