Sorry for being late with our reply (your first answer was almost within 
seconds of the intial question - superb!), but I was only now able to test it.

(find-file "untitled")

does indeed solve our specific problem quite neatly. Maybe one thing could 
still be improved: if the "untitled" buffer is dirty and Emacs asks where to 
save it, the directory now defaults to Emacs' bin directory - so

(find-file "~/untitled")

is an even better choice for us. switch-to-new-untitled-buffer does not seem to 
be part of Emacs 23.2.

Thanks!

Warm regards,
 Stefan
