Yes. And the correct kernel (i.e., the 9.2 kernel) is the one that
did not see the MBR on ada0.

9.2 should also create symlinks for /dev/ad0* to the /dev/ada0* nodes.

As I wrote before, I tried it both ways. It really doesn't matter if
it can't see the MBR and therefore never creates nodes or symlinks for the
slices and partitions. All it had was /dev/ada0. I suppose it may have
created a symlink named /dev/ad0, but the mountroot prompt didn't show any
symlinks, so I have no way of knowing.

Did your boot drive have a MBR on it? Or a GPT label?
