How to merge an unused partition.

Heya folks - here's my issue; I removed a OS from my drive and that freed
up 10 gig. I wish to "merge" the free 10 gig into my FreeBSD file system.

Here's what she looks like via fdisk:

Disk name:      ad1                                    FDISK Partition 
Editor
DISK Geometry:  9729 cyls/255 heads/63 sectors = 156296385 sectors (76316MB)

Offset       Size(MB)        End     Name  PType       Desc  Subtype

         0      10236   20964824        -     12     unused        0
  20964825      66079  156296384    ad1s1      8    freebsd      165
 156296385          2  156301487        -     12     unused        0

So - what do I need to do to take the 1st line and merge it into the 
existing system?

Sorry for the formatting
