Did you reboot the machine after altering the partition table? I know
when I have used some of the partitioning software, I had to reboot the
machine. It has something to do with the kernel having to re-read the
partition table.

Anyway, why are you using fdisk? From its man page:

       There are several *fdisk programs around.  Each has  its  problems  and
       strengths.   Try  them  in  the	order cfdisk, fdisk, sfdisk.  (Indeed,
       cfdisk is a beautiful program that has strict requirements on the  par-
       tition  tables  it accepts, and produces high quality partition tables.
       Use it if you can.  fdisk is a buggy program that does fuzzy  things  -
       usually	it happens to produce reasonable results. Its single advantage
       is that it has some support for BSD disk labels and other non-DOS  par-
       tition  tables.	Avoid it if you can.  sfdisk is for hackers only - the
       user interface is terrible, but it is more correct than fdisk and  more
       powerful  than  both fdisk and cfdisk.  Moreover, it can be used nonin-
