The main use-case of the device is to help you recover easily from a failed BIOS upgrade (either due to using an incorrect BIOS image, due to power outages during the flashing progress, or whatever). The device only supports SPI chips, as used in recent mainboards (in DIP-8 form factor, or via manual wiring possibly also soldered-in SO-8 variants). It can identify, read, erase, or write the chips.
Of course the whole "toolchain" of software tools I used for creating the hardware is open-source, and the hardware itself (schematics and PCB layouts) are freely released under a Creative Commons license (i.e., it's an "Open Hardware" device). The user-space source code is part of flashrom (GPL, version 2), the schematics and PCB layouts are licensed under the CC-BY-SA 3.0 license and were created using the open-source Kicad EDA suite (GPL, version 2).
The schematics, PCB layouts, and other material is available from gitorious:
$ git clone git://gitorious.org/openbiosprog/openbiosprog-spi.git
You can also download the final Gerber files (ZIP) for viewing them, or sending them to a PCB manufacturer.
Some more design notes:
Basic usage example of the device on Linux (or other OSes supported by flashrom):
$ flashrom -p ft2232_spi:type=2232H,port=A -r backup.bin (reads the current chip contents into a file)

I have put up a lot more photos and information such as the bill of materials, the Kicad settings I used for creating the PCBs, the Gerber files and the Excellon drill files and so on.
The first few prototype boards I ordered at PCB-POOL.COM (but you can use any other PCB manufacturer of course), the bill of materials (BOM) lists the Mouser and CSD electronics part numbers and prices, but you can also buy the stuff elsewhere, of course (Digikey, Farnell, whatever).
I already hand-soldered one or two prototypes and tested the device. Both hardware and software worked fine basically, you just need a small one-liner patch to fix an issue in flashrom, but that should be merged upstream soonish.
In order to make it easy for interested users to get the PCBs I'll probably make them available in the BatchPCB Market Place soonish, so you can easily order them from there (you do still need to solder the components though). Note: I'm not making any money off of this, this is a pure hobby project.
All in all I have to say that this was a really fun little project, and a useful one too. This was my first hardware project using Kicad (I used gEDA/PCB, also an open-source EDA toolsuite, for another small project) and I must say it worked very nicely. I didn't even have to read any manual really, it was all pretty intuitive. Please consider not using Eagle (or other closed-source PCB software) for your next Open Hardware project, there are at least two viable open-source options (Kicad, gEDA/PCB) which both work just fine.
To quote from the website:
Qi Hardware, founded on the belief in open hardware, produces mass market quality hardware applying free software principles to consumer electronics. The three fundamental elements in our development are copyleft hardware, upstream kernels and community driven software.
They have put up a timeline for upcoming products, where the 本 NanoNote™ (Ben NanoNote™) — a fully open multifunction ultra small form factor computing device — is the first entry product that is supposed to ship in fall 2009.
The Ben NanoNote is based on an Ingenic SoC (336 MHz XBurst Jz4720 MIPS-compatible CPU) with 3.0” color TFT (320x240), 2GB NAND flash, 32 MB SDRAM, SDHC microSD, micro-USB 2.0. The whole device, including the 850mAh Li-ion battery, weighs only 126g. Detailed specs are available.
Their currently planned setup includes a Linux kernel, u-boot, and OpenWRT as software basis. Personally, I'd like to see a stock Debian running on the hardware sooner or later, of course. The 2GB of flash and 32MB of RAM should be fine for a small Debian system (for instance, my NSLU2 runs off a 1GB thumb drive and has 32MB RAM, and is still very useful).
The code is all GPL'd and available from various git repos, hardware will be CC-BY-SA 3.0 licensed, and they try to use Free Software design and development tools also, including KiCAD for schematics and PCB layout, and probably HeeksCAD as CAD tool for mechanical stuff.
I'm really tired of seeing more and more self-proclaimed "Open Hardware" projects that often don't even mention any license for their schematics and PCBs, or use crappy, self-invented "open" licenses that are not even remotely open in any way. Probably even worse, many hardware related projects use closed-source, proprietary electronic design tools such as EAGLE or OrCAD, thereby ruining the whole project from the beginning by forcing everyone who likes to contribute or adapt the hardware to use non-free software. That's why I was really happy to see the Qi people thrive to use open tools from the beginning! I hope to see more hardware projects use KiCAD or gEDA/PCB for their designs in future...
