I would ask them if they have a fix, as if they do there's nothing
stopping you building a custom kernel with the update.

Its quite common for big companies to not "officially" support until a
release but that doesn't mean they don't have a fix if you know what I
mean :)

In addition to this we're running LSI 2008 based controllers here on
8.2-RELEASE + manually merged in mps driver with ZFS just fine. They
aren't running 4k aligned but they are working well.
