utouch-kmod is not required in 13+ anymore. Built-in hms(4) driver 
handles
absolute mouses too. To enable it just insert in to /boot/loader.conf

hw.usb.usbhid.enable=1
usbhid_load="YES"

libinput can handle such a devices, but it expect them to be tagged by 
udev
as mouse rather than touchscreen. I made a pull request that fixes 
libudev:
https://github.com/FreeBSDDesktop/libudev-devd/pull/21, so you can test 
it
now or wait for it to be merged.
