There is the project in svn.freebsd.org
	base/projects/head_mfi

that should support all current LSI mfi(4) based cards.  We are pretty
close to getting it merged in FreeBSD.  There was a bug I needed to
fix to not act on AEN notifications while booting and more style clean
ups.  It is in pretty good shape when you enable hw.mfi.msi=1.  I'm going
to make that the default.

The driver came from LSI with a bunch more work from some FreeBSD developers
to get it into a form that can be part of FreeBSD.

Thanks,
