I got some irrlicht demos running on the N900. I used the ogl-es branch from irrlicht svn. I had to enable the already existing ogles2 driver, some changes on egl attribs, link with libGLESv2 instead of libGLES_CM and I used the system png-library instead of one from irrlicht. Maybe even more, I am not sure. If you are still interested, let me know. nicolai
