Look into the "simobjects" folder of the FSX demo. You should see an "airplanes" folder in there. That is where you put in the aircraft. Gauge installation is still normal. However, FSX has a different understanding of XML-based gauges than FS9 does. For example: you may see gauges visible on the main 2D panel, but they might not appear properly in the DVC panel or might not appear at all.
As for sound files, you may not hear any sounds of a FS9-based addon if the addon's sounds were aliased to a default or other addon aircraft. For example: the sounds of Mitsuya's BMW addon doesn't work in the FSX demo because the sounds were aliased to the default Cessna 182 and the demo doesn't have the default Cessna 182.
