evdev has a SwapAxes, InvertX and InvertY options, the right combination of
those should get this sorted out.
it also a Calibration option that allows for some calibration if the
cursor position is a bit out from the touch points .

can't comment much in regards to evtouch sorry, last time I looked at it is
a while ago and it didn't build last time I tried to.
if the touchscreen doesn't work with evdev (no clicks are generated) let me
know and we'll fix it.
