Hello,
i bought my Raspi long time before i heard of Emteria or Android on Raspi,
so there was shipped an LCD Touchscreen with it for raspian usage, but now
i tried it out with Emteria and it worked, at least the Screen worked in 800x480
but the Touchscreen works not like intended but more than a Touchpad.
Infos about the Touchsreen and the manual/drivers you can find here:

Thanks,
Dirk
