Hmmm... is it that 0x62, isn't it?

        static struct pci_bits amd_enable_bits[] = {
                { 0x40, 1, 0x02, 0x02 },
                { 0x40, 1, 0x01, 0x01 }
        };

        if (!pci_test_config_bits(pdev, &amd_enable_bits[ap->port_no])) {
                ata_port_disable(ap);
                printk(KERN_INFO "ata%u: port disabled. ignoring.\n", ap->id);

Perhaps this code isn't called at all? It looks I can debug it if you
want so (i.e., if there is no obvious visible bug here).
