I commented out each of the "*_load" directives in /boot/loader.conf;
rebooted; escaped to loader (from the boot menu); used "lsmod" to verify
that nothing was loaded at that time, then issued "boot -s" -- which did
succeed.

Unfortunately, I ran out of time to do further experiments for now; I'll
need to do some work-related things for a while, but thought that this
might at least provide some useful information.

Here is what I commented out:

g1-55(12.1-S)[2] grep KIB boot/loader.conf
# KIB coretemp_load="YES"
# KIB iwn5000fw_load="YES"
# KIB linux_load="YES"
# KIB nvidia-modeset_load="YES"
# KIB cuse_load="YES"
# KIB geom_eli_load="YES"
# KIB filemon_load="YES"

:-)

Peace,
david

Someone who suggests he can "pardon himself" calls for "LAW & ORDER" -- right.
