after I posted this I found apt and dpkg in the 3.5.2 feed. This raises questions too...
Like how to configue dpkg to install only to sd, for example, or , since I am mid upgrade from 5600 to 6000 and haven't been doing experiments on the 5600 I am selling, what is intended with apt and dpkg? Apt was not at all configured. I didn't get to playing with dpkg, but does it digest debian arm .debs from debian.org? Or is it something along the lines of adding functionality to ipkg while doing strictly oz ipks?
