triple keypresses have so far always been misconfigurations. there's a few
autorepeat bugs with evdev though that I've never been able to track down -
lack of time mostly.

yeah, you're right. also, an xorg.conf containing simply

Section "ServerFlags"
    Option "AutoAddDevices" "off"
EndSection

suffices since then the server creates the default keyboard device anyway
(with the keyboard driver). Alternatively, either copy that section into
your existing config or add the line to the ServerLayout section, that'd
work to.
