I've also been an Atlast user for a few years. Can't believe I never heard about your fork of it. John Walker's writeup on Atlast should be required reading for all programmers.
I'm going to try 9atom. I have a newer Eee with no CD drive. With BSD I can convert iso to img, add boot code and be up and running quick. But I guess it won't be so simple with 9atom? If this works, I'll be very happy.
