The problem here is that the i386 nexus_alloc_resource() unconditionally
calls pmap_mapdev() to map any memory-type resource into the kernel.
This is definitely a bad idea; IMHO we should only do this when the
resource is actually activated (and obviously free it when deactivated).
Commentary? Should I just commit the change and see what happens? 8)
