you will probably need to set xorg for two separate displays, and one  
of these can be 3D accelerated, I usually start pd with Gem from the  
display with the projector, and control it with another pd started on  
the other display. This has worked well with 4 screens from 2 NVIDIA  
cards uswing debian, I guess it would be also ok with an intel  
chipset, as it does not rely on twinview or any other fancy graphics  
stuff. Alternatively I believe Gem can open a gemwin on a different  
display to the one pd was started on, check the list archives as I  
have not tried this.
