 that has to be from:
         if (pci_find_device(&pa, agpdev_match) == 0 ||
             pci_get_capability(pa.pa_pc, pa.pa_tag, PCI_CAP_AGP,
              &capoff, NULL) == 0) {
                 printf("%s: can't find display\n", sc->as_dev.dv_xname);
                 return ENXIO;
         }
 but the offset (0x40) doesn't match any object code I have....
