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"

I wanted to, but my Windows computer had no serial port and TI decided to make the USB cable's software not work with a TI-86^*. It's really hard to test a program when after typing thousands of hex digits, one bug or mistyped opcode could lock it up and erase the RAM.

*The Mac version works with TI-86, but not the Windows version so the cable itself is fully capable of connecting to the calculator. I hate it when companies do that kind of shit.
