There has been recent work to port several of the newer Linux file systems 
to FreeBSD, including:

- Pretty old work to get the basic JFS userland tools working (status
   unknown, likely very stale due to the passage of time).

- Pretty recent work to get read-only reiserfs working (committed and in
   the CVS repository).

- Pretty recent work to get read-only XFS working (external repository,
   but publicly available).

Also potentially of interesting:

- Increasingly dated work to port the pre-journalled version of HFS+ to
   FreeBSD, which works well subject to the datedness and
   pre-journalledness of the work.

There's also on-going work on a journalled version of UFS.  I'm sure the 
authors of any of these would be interested in someone lending a hand -- I 
know there have been specific appeals for interest from the XFS crowd in 
the last month, along with test patches, etc, for example.  You might want 
to post to freebsd-fs looking for details on the various projects.
