I just saw where the FreeBSD foundation has awarded a grant to have the OS
ported to the Genesi Efika MX Smartbook portable computer. I would like to
get Squeak running on this platform. Also looking at their MX53 as the core
of a self-made project. I am concerned that the hardware is underpowered,
800MHz Freescale i.MX515 CPU and 512MB RAM. I see where the new OLPC uses
1GB RAM. If we assume that the FreeBSD port will be on par with the
available Linux OS in terms of RAM requirements and performance, is this
enough juice to provide an acceptable level of performance in Squeak?

How difficult would it be to port the existing FreeBSD vm, which is Intel
based, to the Freescale CPU? (
