Oh my. :-(

Can you boot FreeBSD using a kernel on CD and pointing it at the root
filesystem on the hard disk?

Or, a suggested alternative.

Tell Ubuntu to put GRUB in the superblock of the root partition. It
will complain & emit errors, but it works fine, I've done it.

Do the same with FreeBSD.

And use a totally different bootmanager:
