As to OpenGLES, Mesa project has already defined a surface named "EGL_MESA_screen_surface" which you can refer to in mesa git tree, which is also relying on DRI for hardware acceleration . If you mean to create a native pixmap surface and render into FBDev by use of DirectFB,I think it is straightforward, but instead if you wanna implement a DirectFB surface as OpenGL ES surface, wow, Im also expecting that , I think this is for DirectFB 2.0 :)
