While this is true, Promise support seems somewhat problematic for the 4 
port cards - I have a TX4000 which FreeBSD (4,5,6,7) consistently see no 
disks attached to - ever, and a SX4060 that gives ATA semaphore timeouts 
and 'danger Will Robinson' no matter what disks are attached to it... so 
neither of these are any use to me for FreeBSD, unfortunately (I gave up 
and installed Gentoo on the box with the TX4000).

By comparison, I have a 3ware 7506 which works perfectly.

Admittedly, this is all pretty old HW, but I believe there are still 
similar issues with *some* newer Promise SATA cards....
