Well sadly I'm just one and it looks like the price of making such stuff in small quantities is a bit high. I expected something like $15 but obviously I was dreaming. I wonder what is the final price including full SD socket and back door then. Never mind.

I don't know any public download link. 770 and N800 schematic can be googled quite easily. I wonder how can (hypothetically of course) such file appear on similar servers without revealing identity of uploader? Would be nice to have N810 there too.

SDIO is possible in theory but there is no support for it in 2.6.21 kernel. It was added later after MMC stack was completely restructured.

I'm not sure. It can talk in SD or MMC or SPI protocol. If it is not enough maybe those OMAP pins can be reconfigured as GPIOs but maybe serial port pins are better for this.

you need to write kernel driver and talk to it from userspace

Yes, you just need to insert existing kernel module, search this forum for FTDI.
