Cool, thanks. I will be back on monday, and probably have some time on
saturday. But doing d-i work offline without local mirror is no fun.

Well, maybe it will work. It has some limitations though, since lot of
things had to go as modules. In particular i don't believe it will work
with nfs root or such things.
In particular it has not been largely tested on powerpc hardware as the
-powerpc ones have been. I would prefer that both are built for now, and
once we get more wide testing of the -small ones, we may be able to
switch to it.

Well, boot-floppies died because of that, but then they used 2.2 by
default on most arches.

Yep, naturally.
