Yeah, I have issue too, solved by:

  (initrd (lambda (fs . args)
            (apply base-initrd fs
                   #:extra-modules '("i915")
                   args)))

To get fbcon in initrd before udev-service and console-font-service.
I think the 'Console' lines of `dmesg' tell the reason.

I just put it in my config.scm:

  (define (console-layout-service layout)
    (with-monad %store-monad
     (return
      (service
       (document "Setup keyboard layout for console")
       (provision '(console-layout))
       (start #~(lambda _
                  (system* (string-append #kbd "/bin/loadkeys") #$layout)))
       (stop #~(const #t))
       (respawn? #f)))))

Any plan for user services?
Get guix build a dmd.conf for user should be really cool.
