The patch looks good to me.

Side note: you could have avoided a reboot by doing

  sudo herd stop xorg-server

right before ‘guix system reconfigure’, which would have started the new
‘xorg-server’ service.

The log suggests that X detects it.  Is there a chance GNOME would do
something special, like disabling one of the input devices?  Could you
check with a bare-bones window manager whether the tablet is usable?

I have no experience with tablets, so I’m afraid it’s a shot in the
