Sorry for the spam but I'm seeing something else very interesting....
If I boot to Good Mode (F12) and break to the "boot:" prompt, the
system boots if I type /boot/zfsloader. However, if I type
/boot/kernel/kernel (as was seen in the Default setting when I didn't
hit F12),  I get a crash that looks like the following:
-----------------------------------------
