1. in you suggestion. When you are flash the rom, if sth go wrong (lose
power), you will corrupt your rom.
2. are you going to use fallback image with normal image?
If so you can disable the write to last 128K ( fallback image part) via
HW jumper.  ---- No one could change the fallback image without remove
the jumper. Some MB already have that for last 64k.

OK, here's the proposed solution for write protect of the OLPC BIOS.

Short of phishing attacks, I think it should suffice; but I'd like
people here to shoot at the scheme in case I'm missing something.
