Geoffrey Leach from the Fedora list provided a hint to solving this 
problem. I had to add:

none  /proc/sys/fs/binfmt_misc  binfmt_misc  defaults  0 0

to my /etc/fstab, to access the features of the compiled-in binfmt_misc 
code. I then removed the line:

/sbin/modprobe binfmt_misc &>/dev/null

from the /etc/init.d/wine script, as it is no longer needed. I suppose I 
could have left it in, as it does no harm, and it does not complain 
because it throws away the error message. Now the script starts just 
fine, and I can again start my windows applications as before. There are 
no bugs to solve.
