Hi,
I've done some initial porting of libevdev and libinput that may be of help:
https://github.com/jiixyj/libevdev
https://github.com/jiixyj/libinput

I've also written a simple evdev implementation in userspace (no 
keyboard support yet, though):
https://github.com/jiixyj/evdevfbsd

I've got it to expose my Thinkpad trackpoint/touchpad as devices 
/dev/input/event1 and /dev/input/event0, respectively. In X11, 
xf86-input-evdev and xf86-input-synaptics (with evdev backend) 
successfully pick them up. Only small tweaks are needed:
https://github.com/jiixyj/xf86-input-evdev
https://github.com/jiixyj/xf86-input-synaptics

Also you need something like this in xorg.conf:
Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "evdev"
	Option	    "Device" "/dev/input/event1"
EndSection

Section "InputDevice"
	Identifier  "Mouse1"
	Driver      "synaptics"
	Option	    "Device" "/dev/input/event0"
EndSection


xf86-input-libinput should also work, but I barely tested that.

Sorry for not posting about this earlier, but this is still very much 
experimental and probably won't even work for anyone except me right 
now… Still, it might be a good starting point for some "serious" porting 
work. I'll try to polish it up a bit and write some documentation.

Cheers,
Jan
