As far as I know N800 has C55x DSP core clocked at 220Mhz (the same 252MHz core is used in Nokia 770) and also IVA running at 220MHz (1). I did not find much information about IVA, but the following post suggests that it is ARM7 core with some multimedia coprocessors. C55x DSP core can be theoretically good for video and some people have even compiled simple examples for it, but in practice seems like nobody did anything of practical value for it up to this moment. In order to use IVA we would need some documentation and also support for it in dspgateway. Also I don't have any DSP programming experience ... yet
