That looks correct to me, though I wonder why you made a d: partition
out of order in there.  

In FreeBSD 4.xx disklabel, you can just put a '*' in for the size and
it will make a partition of all remaining unpartitioned space.  I don't
have a 5.xx bsdlabel handy, but would be surprised if it didn't offer
that feature.

You will need to be booted in such a way as nothing on that slice
is mounted to be able to write the new label, I believe.
