I dont have one handy to test but the manpage says in the BUGS section
BUGS
     This driver is still in development, it has only been tested on the
amd64
     architecture and has some known shortcomings:
     o   No IR (Integrated RAID) support.
     o   No userland utility support (e.g.  mptutil(8).)
     o   Sometimes the driver gets into a state where devices arrive and
         depart multiple times, without user intervention.
     o   The error recovery code isn't complete.


This along with this thread
http://forums.freebsd.org/archive/index.php/t-4505.html
Indicates the R isnt fully supported, from what i can gather its fine as
JBOD so you can use zfs or one of the geom software RAIDs though.
