Mounting a logical ntfs partition

Hello,

I am running pcbsd 8.1 64bit and am trying to mount a logical ntfs
partition. I have 2 ntfs partitions but the dolphin file manager only sees
one of them (my primary one). Below is my disk layout:

sda1 (ntfs)
sda2 (ext2)
sda3 (pcbsd/ufs2)
sda4 (extended partition containing logical partitions)

sda5 (ntfs)
sda6 (ext4)
sda7 (ext4)
sda8 (ext2)
sda9 (ext4)

For some reason pcbsd doesn't detect any of my logical partitions. I have
tried mounting (using su) ad0s5 (and ada0s5) but the prompt tells me there
is no such file or directory. A quick look under /dev/ reveals this to be
true. I double-checked by issuing the command ls /dev/ad* and the output
listed the following devices:

ada0 ada0s1 ada0s2 ada0s3 ada0s3a ada0s3b ada0s4

Below is the output of the command gpart show:

=>       63  976773105  ada0  MBR  (466G)
         63       1985        - free -  (993K)
       2048  210630656     1  !7  [active]  (100G)
  210632704  681289728     4  !5  (325G)
  891922432   41947136     3  freebsd  (20G)
  933869568   42903552     2  !131  (20G)
  976773120         48        - free -  (24K)

=>       0  41947136  ada0s3  BSD  (20G)
         0  39606272       1  freebsd-ufs  (19G)
  39606272   2330624       2  freebsd-swap  (1.1G)
  41936896     10240          - free -  (5.0M)

As you can see ada0s4 is 325G. This is consistent with the size of my
extended partition. However, when I issue the command gpart show ada0s4 (or
ad0s4) the prompt tells me no such geom.

I use my logical ntfs partition (sda5/ada0s5) regularly under both win7 and
linux. Haiku also detects this partition. I am at a loss as to why pcbsd
doesn't detect any of my logical partitions. Is there any other output that
I can provide to help solve the issue?
