Hmm..  it seem that the MPS driver is in the source on 8-PRERELEASE from 
March 1st 2011, so I think I have it from when I compiled the most 
recent kernel:

# find /usr/src -type f -name \*mps\*
/usr/src/sys/dev/mps/mps.c
/usr/src/sys/dev/mps/mps_ioctl.h
/usr/src/sys/dev/mps/mps_pci.c
/usr/src/sys/dev/mps/mps_sas.c
/usr/src/sys/dev/mps/mps_table.c
/usr/src/sys/dev/mps/mps_table.h
/usr/src/sys/dev/mps/mps_user.c
/usr/src/sys/dev/mps/mpsvar.h

Is there any way I can load MPS instead of MFI to manage my Perc H800 
LSI controller?  Maybe an rc.conf line to add or something?  I looked 
around for MPS documentation but couldn't find any as of yet.

TIA!
