I don't think so but I could be wrong. When "Configure SATA as" was set to "IDE" the HDD was being detected as a SATA drive and showed up as /dev/sda. The only visible difference the change to "AHCI" made was that instead of the drive being handled by the ata_piix it now utilises the ahci driver (which is a much better driver). The other interesting thing is that the probe for the Marvell PATA device occured before the initialisation of the ata_piix driver (or ahci for that matter), so as far as I can tell ata_piix had no chance to grab any ports before the marvell driver initialised.
