1.12 has the ID_SEAT support, so if you set that property through udev the server only adds the matching ones. You'd have to then start the X server with -seat, see the commit message to 159b03e13760920274b573a2bccdbf6a79f059e7 for some detail. If you can't update your server, you can use the ID_INPUT.tags udev properties, together with a MatchTag in your xorg.conf InputClass section to limit devices. not as automatic but it'll get you there with hotplugging enabled.
