It works! It works! I modified the install script in the zipfile, making it install only the gen1 kernel. Camera, OpenGL ES 2.0 and accelerometer are working. I tested it with the Native EGL demo, and it worked flawlessly. Thank you very much to the efforts of all developers here. You helped me to have a better ZTE Racer. Keep the good work! Now I can do some 3D development, finally.
P.S.: There is any way to calibrate the touchscreen's sensitivity? Its very difficult to type with the fingers alone now, I have to use the stylus...
There are some calibration options in Settings -> Device settings but they don't change much the result.
I'm going to include a second touchscreen driver in my next build which will hopefully reduce the touchscreen problems.
