Emiliano, First things first - caveat emptor.
Direct access to the firmware makes it very easy to brick your machine. Do not attempt to use these instructions unless you are prepared to deal with the possible consequences of mistakes and/or failure. Consult OFW experts for the necessary precautions. Second - real answers. There are two user-facing mechanisms available for updating the firmware. One is to put a signed firmware blob in the right place on the filesystem and to reboot. The other is to use a developer key to issue to the necessary words to trigger a reflash directly to the firmware. See http://dev.laptop.org/ticket/5565 for the current debate about the former procedure. To exercise the second method, one uses a developer key and the information on http://wiki.laptop.org/go/Cheat_codes to gain access access to the Open Firmware "ok" prompt. Then, after taking appropriate precautions to ensure the availability of uninterrupted power, one can manually trigger a reflash with two words similar to: get-file u:\q2d07.rom reflash Michael P.S. - if you have to do this for lots and lots of machines, you should probably try to work with us to qualify and release a firmware.
