All right, here is a few questions to Nokia employees in this thread:

Are there any in-house effors to make use of the PowerVR hardware in the OMAP2 chips used in N800/N810? Maybe a limited OpenGL implementation?

If not, is it possible for Nokia to disclose at least some details of the PowerVR architecture? Also, is it possible to disclose low-level specifics of the TI GPS5300 chip inside N810 so that people could play with it and possibly make GPS more reliable?

If not, will Nokia be willing to disclose these details to someone who signs an NDA?
