OK - to continue, while I have a few free minutes.

I have been able to load the old kernel by going to the loader prompt
from the boot menu, and doing
     unload kernel
     load /boot/kernel.old/kernel

That barked about linproc in fstab, so I edited that out.

Then, the next go-round: It complained about mismatches on
daemon_saver.ko - a version mismatch, so I've commented that out of
/etc/rc.conf. It also complained about linux.ko, so that's been
commented out in /etc/rc.conf as well.

I'm now able to reboot cleanly with the old kernel.

After doing 'freebsd-update install' for the second time, I still
can't get 8.2 to boot - same issue, only acd0 is recognized. However,
I'm logged in as root under the old kernel, though I haven't start
XFCE4, and don't have wireless running.

This one is getting to be fun...
