On a system running:

FreeBSD 12.0-CURRENT #0 r326723: Sat Dec  9 12:30:04 EST 2017  amd64

there is a man page, in section 4x.
That's the good news.
The bad news is I see no mention of needing to add anything to
the kernel; it's presented as a Xorg input device.

That did the trick. Thanks!

Seems like evdev doesn't have a manpage, which is why I didn't know to
include it in my kernel config.

Did you add "device evdev"?

Good catch! I did not. Adding now and I'll report back when
buildkernel finishes.

evdev broken

[Shawn Webb]

Hey All,

It looks like evdev support in the kernel is broken.
sys/dev/kbdmux/kbdmux.c contains various unresolved symbols to
different evdev-related symbols.

I have the following options in my kernel config:

options EVDEV_SUPPORT
options EVDEV_DEBUG
options UINPUT_DEBUG

Here's the build failure log:
