Hello Mathias,
...
first, thanks! This solved my problem 90%. BIG Thanks!!
good to hear, but usually the rest 10% are the most difficult ;-)

That's most of what I wanted!! Great. I'm still puzzling over how to change 
the width of the hbox to \textwidth+\marginwidth\margindistance, but for now 
I'm saved. Why do I want a wider hbox? I print white fonts on black 
background, so the left shifted \hbox with a width of (I assume) \textwidth  
looks different from what I wanted. But it works for now...
OK, just in case you run pdfetex (see the e in between pdf and tex ;-})
you can use the \dimexpr ( .... )  primitive:

\def\MyHead#1#2%
  {\vbox
     {\localheadsetup
      \begstrut % is this really needed?
       \hbox {\hskip-\marginwidth\hskip-\margindistance 
         \framed[width=\dimexpr(\marginwidth+\margindistance+\textwidth),
               align=right, %raggedright
               frame=off,
               offset=2pt,
               background=color,
               backgroundcolor=black,
               foregroundcolor=white,
               ]{%
          \ifheadnumbercontent{#1}\kern\numberheaddistance\fi 
         #2}}}}

%\showframe
\starttext
\setuphead[section][alternative=command,number=no,command=\MyHead,style=\bf]
\section{some quick fox jump over very lazy dogs}
\input tufte
\stoptext

If you don't use pdfetex, you might think of switching. Or you could
do some calculation to achieve the same.

Have a nice week,
You, too.
