Assuming you want normal software raid and not the dmraid, then you should turn off raid for those devices in the bios. It might be a later step in the boot process if its an addon card that has its own bios. That should allow anaconda to see them as two separate disks. You'll need a /boot partition that can be raid 1, but can't use encryption or lvm, and the rest you do however you want.
