I think so but we need to act fast.

Actually I'm not 100% sure here: the current FreeBSD ZFS code does not
handle stripesize at all, and thus if you create a pool with the
patch, they will still be ashift=9.  Justin (gibbs@) have a patchset
to address this by the way, but since it's not yet in HEAD I wouldn't
expect it be incorporated in 9.2...

Cheers,
