I had a conversation with Sibananda Sahu, I'm not sure if it made it to here. 

Quick recap:

hw.mfi.mrsas_enable=1 only works on 10.1-RELEASE, it does nothing on
9.3-RELEASE. 

With hw.mfi.mrsas_enable=1 I was able to install 10.1-RELEASE without any
timeouts or other errors. I'm currently running a bonnie++ test to see how
stable things are but it's looking very good so far. 

The difference is easy to tell, with the mfi(4) driver a virtual disk shows up
as mfid0, with the mrsas(4) driver it's detected as da0. 

If time permits today I'll see if I can create a custom 9.3-RELEASE install
with the mfi(4)/mrsas(4) driver removed, to test the driver from LSI (an mrsas
driver can be downloaded for 7.4, 8.2, 8.3, 8.4, 9.0, 9.1, 9.2, 9.3 and 10.0).
The driver from LSI should be newer than the one that came with FreeBSD.
