FOSS netbook

I'm looking for a netbook with the following characteristics:
- dirt-cheap (under the 200 USD mark)
- screen size between 7 and 11 inch
- preferably ARM-based CPU (but x86 is fine too)
- computational power at least half of an Intel Atom N450
- at least 128MiB of RAM
- at least 2GiB of nonvolatile storage OR SD-card reader
- over 6 hours battery life
- no binary blobs required for operation (I don't care if 3d and/or video acceleration require binary blobs, I don't use those anyway)
- open source firmware or "BIOS"

At the moment, there isn't a big worldwide demand for computers with completely free software. This means the small number of manufacturers who do cater to this market aren't going to be getting much revenue to justify the investment of producing big numbers of machines. This will not change until customers change what they want to buy. One possibility for increasing demand is manufacturing specialised computing devices such as home media players, home networking services, home automation modules etc.
