I have used 3ware IDE raid controllers on FreeBSD with much success.
AFAIK the newer SATA boards are also supported by the driver.  You
have to use 3dm (3ware's Linux management server ported over to
FreeBSD) to manage the card.. but 3dm does take care of email alerts
and some other automated functions.  Rebuilds can be done via the
3dm web interface, and I suppose you could write your own tools for
parsing the 3dm output into something more cli-friendly.

I don't think the 3ware cards interoperate with atacontrol.
