--- Comment #2 from Joshua Kinard <kumba@gentoo.org> ---
It looks like 12.1-RELEASE fixed this, in a way.  /dev/input/eventX is
populated now, and it took some tweaking of kern.evdev.rcpt_mask to get the
right devices to start recording events.  I also had to make some adjustmen=
ts
to my xorg.conf file, following some instructions here:
https://lists.freebsd.org/pipermail/freebsd-current/2017-April/065653.html

This leads to a working config block for the Touchpad:

Section "InputDevice"
        Identifier      "Touchpad0"
        Driver          "libinput"
        Option          "Device"                "/dev/input/event3"
        Option          "AccelProfile"          "adaptive"
        Option          "DisableWhileTyping"    "True"
        Option          "MiddleEmulation"       "True"
        Option          "ScrollMethod"          "edge"
        Option          "Tapping"               "True"
        Option          "TappingDrag"           "True"
        Option          "TappingDragLock"       "False"
EndSection


However, a small bug has manifested itself w/ security implications.  I am
noticing that when I type my username and password into the login fields on
slim, that input is apparently being echoed to the virtual terminal that sl=
im
is running on.  This is invisible, however, until you kill X or logout.  Fo=
r a
brief second, when slim is restarting, both the username and password are
visible in plaintext on the console.  Once slim starts up, they can't be se=
en
again.

I suspect this laptop being from ~2011 and a bit slow enhances the delay in
slim's restart, allowing one to actually glimpse the echo'ed text.  I don't
recall seeing this when I was using kbd and /dev/psm0 under 12.0-RELEASE.
