Mesa 7.3 RC1 @ N800

2.6fps in gears in full-screen.
w/o DSP optimization, but at least - it works on real device.

Nokia N8x0 and h/w OpenGL ES

OpenGL EX 1.x accelerator is not connected to screen due to very high screen resolution of screen (i.e. 800x480x16bit) - 768kB only for sigle framebuffer.
upcomming Maemo 5.0/new TI hardware will have a bigger memory for GL accelerator and will have native OGL ES support from scratch.
