This is not necessarily dependent on evdev/libinput.

FreeBSD by default (?) prefers a combined virtual mouse 
(sysmouse/moused), even with evdev.

To get evdev events from separate devices, you need to change rcpt_mask 
sysctl.

With the old FBSD specific interfaces, you have to list them in 
xorg.conf I think.
