Well, the SiI chips doesn't have that kind of functionality, they are 
just plain and simple (and in the 3112 case broken) SATA controllers.

Given the history of SiI (former CMD) and thier (S)ATA chipsets, they 
will need several braintransplants before they'll make a chip that can 
be that advanced *and* work ;)
