I am not clear about what you are trying to do, but fdisk should not 
be mucking with so-called logical partitions.   FreeBSD does not 
really deal with 'logical' partitions'.    Anyway, they are more akin
to FreeBSD partitions than slices.   Slices are the primary division
and partitions are the subdivisions.    fdisk handles creating slices 
and MBRs.  For partitions you use bsdlabel and it handles the boot
record that the MBR hands control off to.

Generally, you don't want to mess with slices or in MS terminology "primary
partitions" with the system running - even if you can find a way.
