I have Intel D975XBX2 with two on-board SATA RAID controllers: one is Intel Matrix and the other is Marvell storage. I have FreeBSD 6.2 with RAID-5 using Intel Matrix Storage. It seems to work fine.

You may want to re-think that option... according to the ataraid(4) man page, RAID5 is not functional (ie. you have about as much data safety as a RAID0 stripe set does):
CAVEATS RAID5 is not supported at this time. Code exists, but it neither uses nor maintains parity information.
