That's why it's not working.

``update-grub'' is unable to mount your UFS diskslice, so it can't
probe it, so it can't find the FreeBSD loader, so it doesn't add it to
the menu.

Can you run an fsck on the FreeBSD slice(s) from a bootable DVD or USB
stick? I think that's where your problem might be.
