Current status of NVSATA & NVRAID support?
 

I have not found documentation for what is or is not supported with nVidia 2200 & 2050 Pro(ck804 & IO4 combo) or the newer MCP such as MCP55 Pro with Linux.

What RAID levels work for kernel 2.6.18 or later; i.p., which for kernel 2.6.27 using ck804 & io4 chipsets?

Using dmraid seems to be the only option. Is there another way to get NVRAID working?
