MFI driver issues

Just for fun I tried building a custom kernel without MFI support, in an 
attempt to force the MPS driver to recognize my devices, but was foiled 
because my boot device (Perc 6i) needed MFI to work, so it wouldn't 
boot.  So I reverted to my old kernel.

I guess it would be most useful if I could somehow force MFI to be used 
on my boot disk as it is now, but use MPS on my 24 JBOD disks coming 
from the Perc H800 SAS controller...?  They are JBOD because I have them 
roped into a ZFS filesystem.
