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 have a 3 years old HP MINI that came with a 9 cell battery. That article was quite old, so i doubt that now you can buy a 2 cell battery HP MINI.

Is slooooooooow. I can only watch videos in youtube at 360px resolution. 480px is slow.

But i don't use it for stuff like that. Mainly i use text editors and ssh connection to remote machines. Damn, i can even run an XP VMWARE virtual machine at acceptable speed for those strange events where i need stuff i can only do in Windows.

The only problem i had so far is the cpu fan that got dirty once. CPU temp was going so hot that the netbook turned itself off automatically after "heavy" use. After opening the netbook and cleaning it with a wind blower everything has been ok so far.

As for coreboot.. i guess is too old (or too jew) to be compatible for that. After running flashrom on it reported Intel ICH7M. It seems that coreboot supports some MB with ICH7, so maybe there is hope?
