Boots now. Only the powersaving works after that but it boots. I'll try to tune the keypad and touchscreen now.

EDIT: Touchscreen works but is inverted on both axes and slightly bigger. Android is working quite fast but unusable at this stage. I like the onscreen keyboard in Cupcake.

Crap. This USB/adb problem with cupcake is really getting on my nerves. Can't connect with adb to the device and can't progress because of that. Any ideas? Tried the udev rule but it doesn't work
