The X server has nothing to do with user authentication [*].  The
display manager does, but don't use xdm, we all hate it and it's not

Typically this has more to do with how you set up PAM.  PAM has no way
of signalling to the authenticating application that an event happened
(like plugging in the card), so I think the way we handled this in
Fedora was to patch gdm to listen for the plug event on dbus and restart
the PAM context when we heard a smartcard event.  But that's just based
on listening to our gdm guy complain about it over lunch, and on:

Note that gdm got rewritten in the meantime, so that patch is almost
certainly not directly applicable anymore.
