If I'm getting it right, you're trying to cerate a new FreeBSD slice on
a disk that already has one. In such a case, you can only boot from the
*first* BSD slice on the disk. This means that you must move your root
partition to the new slice. I may be wrong, but I think the only way out
is to reinstall...
(anyone care to correct me?)
