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.
