It's mentioned as

SEE ALSO
     ioctl(2), syslog(3), atkbdc(4), mouse(4), mse(4), sysmouse(4), moused(8),
     syslogd(8)

in the manpage, even though it doesn't explicitely state that "moused"
is the binary to run.

See "man moused" for details, especially the -r <resolution> option
should be useful. You can combine it with -f for testing. According
to the manpage, something like

	# moused -f -r 300 -a 2.0 -p /dev/psm0 -t ps/2

should be good for testing. To make the settings permanent, you can
code them into /etc/rc.conf, using

	moused_enable="YES"
	moused_port=
	moused_type=
	moused_flags=

with the required values.
