Commit d1cdd7b adds a more pleasant solution whereby one can specify
text to be added verbatim to the Xorg config file, like:

  (define input-class
    "Section \"InputClass" ...")

  (define (my-slim-service)
    (mlet %store-monad ((config (xorg-configuration-file
                                 #:extra-config (list input-class)))
                        (startx (xorg-start-command
                                 #:configuration-file config)))
      (slim-service #:startx startx)))

  (operating-system
    ;; ...
    (services (cons (my-slim-service) ...)))

But more importantly, it seems to be that these things are supposed to
work out-of-the-box nowadays.

Commit c2ee19e adds the libinput Xorg driver in the server configuration
file, which might help.  It is described as the “future” of input
drivers:
