Information is hard to find, very little on Intel's site.
Here's some basic info, you probably have seen these, posted for others to see if they haven't already.
RAID From Wikipedia
Advanced Host Controller Interface (AHCI)
And the rest is really hard to find, mostly discussions a couple of benchmark tests, not much info really.
As you mentioned, I find this rather strange, even an Intel search gives old information.
Other misc info found, that might be of interest.
