I know, and in fact C-h f run-scheme shows that the function doesn't
belong to Geise even after loading it.
But I've got the impression that Geiser modifies some underlying
functionality used by 'xscheme'.

I'm using version 0.7 with emacs 24.5.1. I did install both of them
with the functional package manager guix
http://www.gnu.org/software/guix/

Yes, I can reproduce it with 'emacs -Q':

1) In '*scratch*' execute: (require 'xscheme)

2) M-x run-scheme -> everything works fine.

3) Kill the MIT scheme process and the '*scheme*' buffer.

4) In '*scratch*' execure:
  (add-to-list 'load-path "/home/beffa/.guix-profile/share/emacs/site-lisp")
  (require 'geiser-install)

5) M-x run-scheme -> I'm asked about the scheme implementation to use.
The only allowed choices are: guile racket and chicken.
