Thank you very much for taking the time to reply, Kevin!
OK to confirm I've cleaned up, and nothing might conflict. Here's what
I have:
# pkg info | grep drm
libdrm-2.4.99,1                Userspace interface to kernel Direct Rendering Module services
# pkg info | grep mesa
mesa-dri-18.3.2_9              OpenGL hardware acceleration drivers for DRI2+
mesa-libs-18.3.2_4             OpenGL libraries that support GLX and EGL clients

Following your advice, I pkg install drm-fbsd12.0-kmod-4.16.g20200221
ensure I have the module kld_listed in rc.conf(5). Bounce the box, and it
locks up with a trap 9.

So I pkg delete drm-fbsd12.0-kmod-4.16.g20200221; comment the kld_list line
bounce the box. Try a different route; pkg install drm-kmod which results in
drm-fbsd12.0-kmod: 4.16.g20200221
drm-kmod: g20190710

bounce the box; again, trap 9.
I'm booting efi, if that makes a difference. So all I seem to be able to
safely load is drm-legacy-kmod. Which no-longer seems to be compatible with
X and friends. I don't know how you do it. But thank your lucky stars. :)

Thanks again!
