Well, if you have the choice between and graid5 and gvinum I'd might go with
graid5. It's not included in head(yet) but from what I've read on the
mailinglist it seems to work (also included in FreeNAS). But I can't really
say anything as I've not tried it much. If you want to try the gvinum version
in progress (quite stable, although a few knits for advanced usage) can be
found here:

http://svn.freebsd.org/base/projects/gvinum 

Should work on both HEAD and RELENG_7.
