And --load= too :-)

Thanks for the pointers!  You helped to figure it out.  And the system
is awesome!!  The only big issue I've noticed so far is: the screen
resolution was 800x600 for me and xrandr didn't give any other option.
"/var/log/Xorg.0.log" told me that the module for my videocard ("sis")
wasn't loaded.  I looked at (gnu services xorg) and found that not all
available "xf86-video-…" modules are placed at "xserver.conf".  Is there
a reason for that?

Hm, perhaps I just need to install "xf86-video-sis" package (I should
have tried it before asking).

Also I have a question.  I usually add some custom lines to "xorg.conf".
I suppose currently there is no other way to do it but to make my own
xorg (slim) service.  Right?
