Hmm. It _should_ actually only be using memory I/O anyway:
/* type 3 adapters have an I/O region we don't use at base 0 */
rid = (sc->mlx_iftype == MLX_IFTYPE_3) ? MLX_CFG_BASE1 : MLX_CFG_BASE0;
sc->mlx_mem = bus_alloc_resource(dev, SYS_RES_MEMORY, &rid, 0, ~0, 1, RF_ACTIVE);
(the 1164 is a MLX_IFTYPE_5 adapter)
