So far...
Finally zooming works correctly, so you'll get android apps in full screen.
Touchsscreen calibration were rewrited to support dinamic zooming (but to make sure that it will work fine for everyone, someone post result of this shell command: #cat intstorage/.edge/.esi-system/calib_values).

Now working on keyboard (probably the best way is to fix some issues is to completely rewrite keyboard input method which will work when android displayed on e-ink or to use external keyboard) and power saving options improovement (if someone know where to find Marvell's pxa168 developer manual --let me know).
