Thats right! Kivy is using OpenGL ES on Android via python-for-android. The guy who's working on the OpenGL code already put some effort as he made a ssh connection to my N900 and tried to make it working, but, as he says in the issue report on github, the OpenGL headers are out-dated (fix needed) and the OpenGL ES build which I made using scratchbox is acting weired.. so someone who knows OpenGL ES on maemo well could solve that problem
