I would say there is some progress in those projects! A "very active
development" IMHO looks different!

But it is still the case that you don't find the project when you browse
http://www.handhelds.org/projects!

Ok, so let's start! Where is a linexec binary, what we can try? To
compile it outselves is no option here, because as far as I've
understood this is a wince binary and so we need a development
environment for wince! I think that's definitely not what most of us
have (and what we are looking for)! So it would really be great if
somebody can provide us with a binary!
Who is able to do so?

OK again, let us start!
1. What is a good Toolchain to start with? (A pointer to a tar archive
would be great.)
I hope this is a cross environment for i386, so that it runs on a normal
linux system and produces code for arm.
2. Where is a description how to build a kernel for an existing
platform, eg. 36xx. Where is a .config file?
(I'm not familiar with building a kernel for the arm architecture, my
experience is from building normal 386 kernels, sorry, if I'm missing
the point!)
3. We need a configuration (.config-file or a list of options to answer
in the make config). Who is able to provide such a configuration? If
this is not available let us discuss, what we really need: What is this
minimal configuration? I assume that this is a system with a serial
console. What do we additionally need? I assume, no flash, no
touchscreen, no CF, no SD, no USB.
4. What are the next steps? I assume we need a ramdisk with some basic
commands in. Can we use parts of a complete distribution like familiar
or so here?
5. 1st shell prompt!!!!

Agreed, but this is the 2nd step anyway!
