I see some cases where the cache behaviour of memory for NetBSD differs
from the upstream, linux ones. I wonder if it can help to make them
#ifdef __NetBSD__ ... write-combining
err = -bus_space_map(opregion->bst, asls, OPREGION_SIZE,
base = memremap(asls, OPREGION_SIZE, MEMREMAP_WB);
jared states an equivalent to MEMREMAP_WB is BUS_SPACE_MAP_CACHEABLE.
