I'm on vacation right now, and sort of semi offline (you know, the
undocumented ACPI S-1 "wife mandated offline state" :-)

In addition to what you already have discovered, you _may_ have an
issue with your bsd disklabels (too).

I would probably do it like this (assuming you have remote console):

Put 4.8 kernel and a 4.8 mfsroot image (with plenty of fixit like
stuff, size is not a big issue if you boot this from disk) on the
5.x system, boot that kernel using the mfsroot as root filesystem
and try to do the surgery from there.

The advantage to this approach is that you can explore the issues
returning to your 5.x installation and adjust your approach.
