Thanks Greg, 

The code seems to being doing what its supposed to be doing (afaik):

/**
 *      sis900_get_mac_addr: - Get MAC address for stand alone SiS900
 *      model
 *      @pci_dev: the sis900 pci device
 *      @net_dev: the net device to get address for 
 *
 *      Older SiS900 and friends, use EEPROM to store MAC address.
 *      MAC address is read from read_eeprom() into @net_dev->dev_addr.
 */

static int __devinit sis900_get_mac_addr(struct pci_dev * pci_dev,
struct net_device *net_dev)
{
        long ioaddr = pci_resource_start(pci_dev, 0);
        u16 signature;
        int i;

        /* check to see if we have sane EEPROM */
        signature = (u16) read_eeprom(ioaddr, EEPROMSignature);
        if (signature == 0xffff || signature == 0x0000) {
                printk (KERN_INFO "%s: Error EERPOM read %x\n",
                        net_dev->name, signature);
                return 0;
        }

        /* get MAC address from EEPROM */
        for (i = 0; i < 3; i++)
                ((u16 *)(net_dev->dev_addr))[i] = read_eeprom(ioaddr,
i+EEPROMMACAddr);

        return 1;
}

: which is checking to see if the device is present, and if not
returning a sane value, exiting.

I'm getting the feeling this has something to do with that unknown
device? (of course, speculation on my part is usually a bad idea)

Unfortunately, its an on-board chipset. 8\
