Recommended SATA controllers?

[Dieter]

Looking for some form of SATA controller with good support.
Currently running FreeBSD 6.2.  Bonus points if it also works well
with NetBSD & Linux (machine triple boots).  I don't need RAID.

Has there been any progress getting a driver working for Silicon Image 3124?

Or any SATA controller with NCQ?

Do any of the USB to SATA controllers work well under FreeBSD?
Or 1394/firewire to SATA?

PCI slots are full.  PCIe-x1, USB-2, firewire-400 available.
