If addr2line can be trusted here then : 

eris# addr2line -e /usr/lib/debug/boot/kernel/kernel.debug 0xa8c918
/usr/src/sys/powerpc/powermac/macgpio.c:356

   347  void
   348  macgpio_write(device_t dev, uint8_t val)
   349  {
   350          struct macgpio_softc *sc;
   351          struct macgpio_devinfo *dinfo;
   352
   353          sc = device_get_softc(device_get_parent(dev));
   354          dinfo = device_get_ivars(dev);
   355
   356          if (dinfo->gpio_num < 0)
   357                  return;
   358
   359          bus_write_1(sc->sc_gpios,dinfo->gpio_num,val);
   360  }
