That worked beautifully. The start position (or what the first number is) changed, but everything seems to work.
Now it looks like this:
root at kg-ibook# gpart show ada0
=>       18  117210222  ada0  APM  (55G)
         18     262190        - free -  (128M)
     262208   52626616     2  apple-hfs  (25G)
   52888824       1600     1  apple-boot  (800k)
   52890424   29358528     3  freebsd-ufs  (14G)
   82248952   34961288        - free -  (16G)

And gpart list:
root at kg-ibook# gpart list ada0
