Touchscreen Support

Hey there,

is there any posibility to get an updated list of supported touchscreens?
is there really only 7 compatible old screens?

We own 2 Hedge Hog4 and diferent brand screen like samsung, Hans G, Acer and non of them work correctly (we see the image but touch doesn't work)
We can calibrate them, but when you touch they become crazy
cheers
