I have the same issue , which I reported on Bug #426340:
After a lot of trial and error I figured out that calibration points order is
different between driver and calibraton program.
For the calibration program xy0,xy1,xy2 belongs to upper-left,upper-center and
upper-right but for the driver 0.1.2 belongs to upper-left,middle-left and
bottom-left
My workarround:
Edit /etc/init.d/xserver-xorg-input-evtouch and change the mapping of
the points with this values:
hal_set minx $MINX
hal_set miny $MINY
hal_set maxx $MAXX
hal_set maxy $MAXY
hal_set x0 $X0
hal_set y0 $Y0
hal_set x1 $X3
hal_set y1 $Y3
hal_set x2 $X6
hal_set y2 $Y6
hal_set x3 $X1
hal_set y3 $Y1
hal_set x4 $X4
hal_set y4 $Y4
hal_set x5 $X7
hal_set y5 $Y7
hal_set x6 $X2
hal_set y6 $Y2
hal_set x7 $X5
hal_set y7 $Y5
hal_set x8 $X8
hal_set y8 $Y8
