What was that error? P4's features are a strict superset to
those of P2 or P3. This error might have to do with something
completely different like faulty hardware or damaged data.

It was unnecessary to chroot, I think. Try the DESTDIR option:

cd /usr/src && make world DESTDIR=3D/path/to/mnt
cd /usr/src && make kernel DESTDIR=3D/path/to/mnt
mergemaster -D /path/to/mnt

You'll also need to set the disk active. Try something
like "fdisk -a /dev/ad1", but I'm not experienced in this
wizardry.
