No such documentation exists, I'm afraid.

I used the Linux driver, along with some support from an engineer that 
was at 3ware at the time.

However, I'm a little perplexed when you say that the FreeBSD driver 
can rebuild an array; it can't.
There's an interface for the 3ware management tool (3dm) which is 
certainly capable of instigating
an array rebuild, but most rebuild operations are undertaken 
transparently by the card.
