Sata-300 Controller Support

I recently purchased an HP XW8600 workstation.
I'm using the onboard Intel 631xESB/632xESB SATA RAID Controller in a RAID 10 configuration.

I get the following error during installation of OpenSuse 10.3

The partitioning on disk /dev/sdb is not readable by the partitioning tool parted, which is used to change the partition table. You can use the partitions on disk /dev/sdb as they are. You can format them and assign mount points to them, but you cannot add, edit, resize or remove partitions from that disk with this tool.

Is there support for this particular array controller? Or is there some other other step I need to perform to get the SUSE installation to recognize the array?

Any advice is greatly appreciated.
