QEMU image for firmware 703

[Urko Fernandez]

The school federation in my region lend me one of the two XO-1 they got
with the G1G1 program. I'm going to give a presentation next week and
I'm trying to get collaboration between sugar-jhbuild and the XO with no
success. Both are connected to xochat.org but only sugar-jhbuild sees
the other. 
I'm trying to find an 703 Qemu image (ext3) but all I can find is
firmware 625 here:
http://olpc.download.redhat.com/olpc/streams/development/
and the jffs version of 703 here:
http://download.laptop.org/xo-1/os/official/703/

Is some of the joyride versions posted here the 703 firmware?

Thanks,
