Well, in fact, I can make my SM501 card attachable for loginctl when I load the
kernel module "sm501fb", but Xorg won't load on this card with the generic
"fbdev" video driver and the automatic xorg.conf generated by systemd. This is
the relevant part of my Xorg.1.log

Anyway, all I need is an option to customize the Xorg command line executed for
non-fully-hot-pluggable graphics devices, so I can e.g. pass a custom config
file with a "Device" section properly set for my card, using the native Xorg
video driver "siliconmotion", instead of "fbdev". However, it's not clear to me
if this should be made in loginctl itself or in a display manager. Just for
comparison:

- in Huo & Cameron multiseat-optimized ConsoleKit approach, the Xorg command
line can be customized just by adding a new display template file in directory
/etc/ConsoleKit/displays.d, and using it when loading a new session (I really
like this approach);

- in LightDM, the Xorg command line can be customized in its own config file,
lightdm.conf.
