sid
For building live-images with live.debian.net I setup a temporary apt-repository with a (manual) copy of the kernel packages and the xorg packages:
deb http://layer-acht.org/debian sid olpc deb-src http://layer-acht.org/debian sid olpc
This should probably be moved rather sooner than later to http://debian-olpc.alioth.debian.org/ 
packages from quozl
