     Hmmm...  Did the stage 2 boot loader change in some important way for
i386 between 8.x and 9.2?  I would not have thought that putting stuff into
/dev would have depended upon anything in the loader.  Other than the loader,
what else does installkernel leave unchanged?
     BTW, I just realized that I forgot to mention in my original message
that the first 9.2-RELEASE kernel I tried was built with both

options		GEOM_PART_GPT

and

options		GEOM_PART_MBR

When that didn't work, I tried commenting out the first of those (GPT), which
was the way I had had them in my 8.2-STABLE kernel.  The change made zero
difference that I could see.  The messages at the point of failure were the
same either way.
