I know of an developer environment that can help in creating a special iLiad linux distribution. This environment is called T2 (
http://www.t2-project.org/ ).
T2 already support the Arm architecture. So it will only be a matter of creating a so called iLiad target. I only wonder how a created distro can be installed on the device.
The best thing would be if the iLiad can boot from CF. This would make playing around with it a lot more "brick safe".
my 2 cents
