I do have Intel HW here as well now, (big thanks go to FreeBSD Systems 
and Yahoo for making that possible), and I am looking into the matter.
I have most of the problems solved regarding support of the chipsets, 
but very differently from your work.
I havn't looked into hotswapping SATA much yet, as there isn't much HW 
around that actually supports that yet, but that will most likely chage 
soon.

As I said I have code for reading the Adaptec case (which btw is used on 
all the Intel boards I've seen so far) and that will get in when the 
Intel stuff gets committed as well.

I'm sorry if this sounds a bit harsh, but your work conflicts pretty 
much head on with the way I want this to move along. However code to 
read/write the RAID config (AMI way I'd guess) would be welcomed as I 
only have the descriptions for that done, but no code yet...
