Ah, i see (i was trying on platform-drivers-x86 but master branch, sorry)
latest version is rebased on top of it, i seen the reason it didn't
apply was that the addition
 to sparse_keymap was already done in 1c8284 by Stefan Brüns (whoops :)
However still needs the initialization part, so booting or
modprobe with the device already in tablet mode would initialize the
correct state
