The reason for this limitation is due to the fact that instancing w/mapping overrides is broken in the 3ds Max SDK. I notified the max devs about this last year and they are aware of it, but for the foreseeable future it will be a limitation.
For small numbers of particles you could manually sample the colors from your mesh using a Script operator and then draw them as points using the provided drawing methods (I believe "DrawMarker" is the command, but you'll have to check the Script op API)....but it will be very slow for millions of points.
