| You should try the updated mfi(4) driver that Doug (cc'd) is going to soon
| merge into HEAD.  It syncs up with the mfi(4) driver on LSI's website which
| supports several cards that the current mfi(4) driver does not.  (I'm not
| fully sure if the 9240 is in that group or not.  Doug might know however.)

Yes, this card is supported with the mfi(4) in projects/head_mfi.  Looks
like we fixed a couple of last minute found bugs when trying to create a
RAID wth mfiutil.  This should be fixed now.  I'm going to start the
merge to -current today.  The version in head_mfi can run on older
versions of FreeBSD with the changes that Sean did.

Note that I wouldn't recomend the 9240 since it can't have a battery
option.  NVRAM is the key to the speed of mfi(4) cards.  However, that
won't stop us from supporting it.
