Why are they hidden, otherwise I expect the technical reasoning.

This also makes sense and answers my questions if drivers will work with
all kernels. Are there no problems with 68000 code and Coldfire here?

2 days ago, I would have fully agreed. Now that I took a deeper look at
them, I think there is a structure visible. Maybe a generic readme file
on toplevel would help here?

I can imagine.

I also discovered that the binary distribution differs from what the
sources can built. I could build various MintNet utils such as ifconfig
in my local build tree but I could not locate them in
http://www.fairlite.co.uk/FreeMiNT/builds/freemint/freemint-1.18-12102013.tar.bz2 which I decided to takeapart this morning....

Can I use my versions of the tools with the official kernel?

Another thing: this release has mint/1-18-1 as the sysdir. Is this the
same for a kernel built from trunk source or is it 1-18-cur there? (Or
even 1-19-...?)

Thanks for your explanations, the mystery on FreeMiNT, its components
and build process starts to dissolve rapidly :)

Regards,
Matthias
