Hi Jeff,
(Contacting you because you seem to be the maintainer of drivers/ata/ahci.c )
I recently bought a Promise FastTrack TX8660 (8xSAS PCIe-x4 SAS HBA).
The board can be switched either in RAID or in pure SAS JBOD mode by entering
into the firmware menu at boot time.
I don't care about the RAID mode (I am using software raid) but sadly even the
direct SAS mode is not working out of the box using a vanilla kernel.
I did a few googling and found this :

Basically a guy saying that adding { PCI_VDEVICE(PROMISE, 0x3781), board_ahci }
in the ahci_pci_tbl[] in drivers/ata/ahci.c do the trick with this board.
I gave it a try and ... it just works.
Here is an lspci output of the card
