Unfortunately there are no drivers that allow programmers to take advantage of the 3D hardware inside the N800... (yet?)

If you sign up to the PowerVR Insider program (for developers) here:

there is a box you can check to be informed about "N800 drivers", but that seems to be the only reference I can find that such drivers might be in development and may exist someday. The developers at Nokia seem to pretty much sidestep the issue if you bring it up with them on mailing lists, etc. There is some question as to whether such drivers will even help that much because there are serious bandwidth issues that hobble the N800's display, making it much less capable for fast action gaming than it should be given the overall hardware specs.
