Never mind -- found one here:

The SATA chip is clearly a 88SX6091-8CZ, which is a PCIX 8-port controller.
Since it is sitting on a PCIe card, one must assume there's a PCIe-to-PCIX
bridge hidden under that huge heatsink.

So if the card does not work in the chip_608x mode,
there's probably some funny business in that bridge chip.

Maybe it works *only* in the proprietary RAID mode (?)
