If you run moused(8), the device in XF86Config should be /dev/sysmouse
and the protocol should be set to "SysMouse". I assume you run moused(8)
with something like

  moused_flags="-p /dev/psm0 -t auto"

in your /etc/rc.conf . If so, does the mouse work on the console? If
not, you might want to read psm(4). I had to add


to /boot/device.hints . Note that this is not availeable in FreeBSD 4.x
but instead you will need to add those flags to your kernel config. Find
a line that says

  device psm0 at atkbdc? irq 12

and make it

  device psm0 at atkbdc? irq 12 flags 0x100

Hope this helps, it worked for me.
