nForce2 RAID MCP (SATA) support?

Hi folks-

I'm trying to find out if there is support for integrated nForce2 RAID MCP 
SATA controller already or planned in the forseeable future.

I'm setting up a system with an MSI K7N2 Delta2 Series motherboard.  Booting 
from 5.3-R, the controller is detected as a generic ata controller and runs 
the disks at UDMA33.  I'm actually quite impressed by the hardware even 
without a specialized driver, but I'd like to know what to expect in terms 
of support.

Thanks!
