Marcus -

You are absolutely correct that my previous comment will not solve the
problem. I have just changed the build scripts so that the rainbow
builds will produce both ext2 and jffs2 images; when the next build is
run, you should be able to use the ext2 image to test out the software.

Incidentally, it is reasonably straight-forward to configure QEMU's
network access, so if you're able to hop on #olpc this evening, I can
probably get that working for you.

(The summary is that you tell QEMU to use the tun device to generate its
own interface, you manually configure both the host and the
client-sides of the interface, and you add a suitable firewall rule to
do source-NATing for the relevant IP addresses.)
