I've tested the current master (9b0803b) on our two Elo screens and normal/inverted rotation calibration works fine. The problem comes when we rotate the screen to the left or right. Then the returned calibration output looks like this: https://gist.github.com/3031786. Compared to the state before the changes from 21/6 onward, it's absolutely broken. Before our issue was that when rotated left/right the axis invertion would be wrong and a second run would fix it. Now it's unusable.
