Once that is complete we should have a 2.6.25 kernel that can run on the N810.

Now the Android part:

1) diff the stock 2.6.25 kernel with the Android kernel to get the Android changes
2) apply this patch to the kernel obtained above

After that we should have everything we need for the kernel right?

I would be very interested in the 2.6.25 kernel with Nokia patches.

But I'd be surprised if your task was as easy as you think it is; for example, what do you do if the same code has been modified by both Nokia and Google? Whose code do you take?

I'd be interested in collaborating, perhaps starting a project.

I've been going through the patches, lots of work.... but I'm sure it's doable.

In theory, yes. But, in my opinion, it'd be much more valuable to port it to display on X, than to have it write directly to yet another specific piece of hardware.

Displaying to X would probably be valuable to all X windows compatible platforms (other linuxes and unixes, even Macs, which have an X add-on ... and maybe even Windows, if there's X add-ons for that).

I agree with you that X11 is the better target, but I'd point out that lcuk's work does not use standalone framebuffer access, but XV; such a port to XV would be more broadly applicable than N8x0 only.

And yes, both my NT boxes are running X servers. Cygwin's the only thing that makes sitting in front of NT all day bearable.

I never said it was easy. I was just outlining what steps I thought needed to be done.

I'm so very much out of my depth here; but I'm looking forward to seeing what the True Coders here can do... Like I said, I'd be very interested in the half-way point, the new kernel with the Nokia patches applied. I can see all sorts of reasons why that might be very very valuable, not least of which is that, if I were Nokia, and I were developing a new OS for a new, powerful platform I was building, I'd probably start with a newer kernel. And it seems to me that having that newer kernel also running on older Nokia devices might be a step in the right direction to backporting some, if not all, of the new OS (especially important, low level stuff) to the older devices...
