This change to the aac(4) driver comes from Adaptec's vendor driver,
but it might break older controllers (Dell PERC 3, Adaptec 2200, etc.)
and/or controllers running with older firmware.

If you're able to test with this change on such an adapter, please let
me know whether or not it works for you and which controller and
firmware you have.  If the driver is going to fail with this change, it
should happen at attach time.  (Make sure you still have a kernel
without the change saved away.)

If it does fail, please test with the patch at
http://people.freebsd.org/~emaste/patches/aac_fwstatus_new_comm.diff
and let me know if that fixes it.

Thanks,

Ed
