| You should try the updated mfi(4) driver that Doug (cc'd) is going to soon

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.
