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"

Don’t expect the three-cell lithium-ion battery to last much beyond 2 hours on a single charge, but using a netbook for longer than that taxes the eyes and brain.
Uh, I've been using my netbook sometimes for 12h runs.  Maybe you should go see an ophthalmologist.

The keyboard alone is worth the HP Mini’s relatively high price of about $500.
For 30$ I got a separate, very comfortable USB keyboard which I sometimes bring along with me if I need to do lots of typing.

Motherboard's gonna fry, bro.  Oh and the BIOS is obviously closed-source, and coreboot incompatible like every other netbook.

I have been told
