This does the job.  The X server now drives all 3 grapics outputs 
without any problems that I've noticed.

For the record, the hardware is a CompuLab AirTop with an Intel Iris Pro 
P6300 grapics chip (i.e i915).  I updated the kernel to:

uname -a -->
FreeBSD maxwell.mannynkapy.net 12.0-CURRENT FreeBSD 12.0-CURRENT #1 
r324944: Mon Oct 23 20:52:58 PDT 2017 
root at maxwell.mannynkapy.net:/usr/obj/usr/src/sys/GENERIC  amd64

and fetched an up to date /usr/ports, where:

root at maxwell:/usr/ports/graphics/drm-next-kmod # cat distinfo
TIMESTAMP = 1507314617
SHA256 (FreeBSDDesktop-kms-drm-g20171006-63426fd_GH0.tar.gz) = 
4ccc9237dde238d28a2a5fc57d62531b994d1c8f0ac1e5a07976636b1923927f
SIZE (FreeBSDDesktop-kms-drm-g20171006-63426fd_GH0.tar.gz) = 6677599

Then I did a 'make install' and followed the directions about rc.conf 
and /etc/group, and the X server came up in working order with the 
default configuration.

I notice that TrueOS has a config file for the X server, but the only 
difference from the default built in one seems to be that the default 
loads a few extra drivers, then sees they aren't needed and unloads them.

Thanks everyone for a pleasant, instructive, and successful experience!

If anyone has further questions about the hardware or configuration I'm 
using, feel free to ask.

Regards,
