modulename_load="YES" is the syntax used in the loader.conf file.
"load modulename" (without the quotes) is the syntax used at the
loader
prompt.

So at the loader prompt, try the following:  load mpr
Or possibly:  load mpr.ko
Or, to get right finicky:  load /boot/kernel/mpr.ko

You should be able to use "ls" to see what .ko files are available,
and in
which directory, in order to load them.

Thanks Freddie and Miroslav.

I tried "load mpr" earler, but it complained it couldn't find it. 
I tried
again a few minutes ago using "load /boot/kernel/mpr.ko", which spun
for
a bit then complained it couldn't load it before the kernel.  I then
loaded the kernel (by full path), and tried again, with no response.  Just
an immediate prompt.  I tried "load /boot/kernel/zfs.ko" as well, in
case
mpr.ko was already still in memory, but that also returned an immediate prompt
without saying anything.  So, I think I still have something wrong with my
attempts to "load".  Should loading the mpr.ko before the kernel work?
It
didn't with my last attempt (which I realize now was 12.0-RELEASE,
not 12.1-RELEASE).
