David




StarTech 4 Port PCI Express x4 SATA II Card Model PEXSATA24E

Justin.




Chipset: Marvell 88SX7042
SATA Connectivity: Use four internal ports at the same time or two internal and two external ports 

Which is fully supported in the latest kernels (didn't try an old kernel):

linux-2.6.25.10/drivers/ata/sata_mv.c

  /* Marvell 7042 support */
  { PCI_VDEVICE(MARVELL, 0x7042), chip_7042 },
