Hello, I'm new user and I have a little pbm to mount an existing ext2 partition

I have on the same HD (46Go) in this order
  - a 4Go partition for NetBSD
  - a 42Go partition of data in ext2 format

I'm a bit lost with the disklabel.
I have tried to mount every device possible... but none works.
So, I suppose that I have to add in my disklabel my ext2 partition,
but I don't relly understand what I have to add (see my disklabel below).
All my tentatives where unsucsessfull.
Maybe I can't mount a 42Go ext2 partition...
Please.. Help
