The link sully posted indicated that a hardware RAID controller was supported, this is dealing with onboard SW RAID. It depends on the RAID chip set, everything will work with true hardware RAID as the controller will mask anything on the disk back end and present a virtual "drive" to the host.
I haven't found anything that will support the ICH10R controller yet, every writeup I see on any Linux distro the neckbeards refer to software RAID as "fake raid'.
