Can you get in contact with the Xorg mailing list on that issue? As far as I
understand the XI2 plans raw input processing is planned and a high
priority(not only for wine, but also to layer DGA emulation on top of it). I
barely know the details, and since you worked on this it would be very
helpful if you talked to the Xorg guys
