Read the documentation about disk slicing. It should be possible for
you to get what you want, since you're apparently not intending to
boot from it. (As the docs are telling, the boot sectors are not yet
slice-aware.)

Hmm, the FreeBSD slices will be /dev/sd0s2 and /dev/sd0s3 then. I
assume you will have to swap the physical location of entries 2 and 3
in the partition table then, so the boot code will find your current
FreeBSD slice first and boot from it. Properly done, shuffling the
partition table entries around should not lose any data.
