I do support the *hardware* that is the SiI3114 chip. That means you 
will get access to the individual disks on the 4 SATA channels just like 
any other (S)ATA controller.

Now the RAID "stuff" you are talking about is all done in *software* so 
  it depends on the BIOS type/vendor and what type of metadata it uses. 
Software RAID's are supported from Promise/HighPoint/LSI as I stated 
above, if thats not what you have the ATA driver doesn't know how to 
pick up the metadata from the disks, and therefore doesn't know what the 
RAID looks like.

However, atacontrol can create at RAID for you on any type of (S)ATA 
controller, you just have to live with certain restrictions, se 'man 
atacontrol' for details.
