I have similar problem. I found the only way to set defaults for a new input device (which also applies to Xorg re-adding the same devices at some arbitrary times like suspend) at runtime, without restarting Xorg to pick up modified xorg.conf, is to set xkb* udev properties on a device (for example by adding new rule and reloading udev).
