ext3 slice not visible

First of all, hello!

I have a question about partitioning scheme on my hard disc. The attached screenshot presents partitioning as shown by gparted on linux.
Now this is output of gpart from FreeBSD

Code:

My question is why FreeBSD does not see slice labeled vdat? gpart report it as a unused space. There is even no device in /dev for that slice.
It seems to me that FreeBSD somehow doesn't see partitions that are following unused space (but of course I might be wrong). I partition discs using gparted if it matters.

My system is

Code:

$uname -a
FreeBSD DaemON.localhost 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec  4 09:23:10 UTC 2012     root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

Another thing that I don't understand is why ada0s5 is shown as MBR followed by unused space.

Code:

          0  662198272  ada0s2  EBR  (315G)
          0          1          - free -  (512B)
