It was the other way around. I happened to have an "old" open shell
where id was still seen as 400, and *there* did ssh work; but when
I closed the window and opened a new shell, my numeric user id is
now 121833 and ssh does not work anymore at all.

You mean: changing all files to owner 121833? That is: Should I do this:

  chown -R 121833 ~

But for the test of ssh, wouldn't it make more sense to chown the id_rsa
file instead? Note that on my system, it is not in ~/.ssh, but in
/cygdrive/h/.ssh. So I did a 

  chown 121833 /cygdrive/h/.ssh/id_rsa

but ssh still fails.
