The driver needs to talk to a pppauthd of some sort I suspect. Auth certainly has to be done via user space.

NFS kind of vaguely does it. Basically its something like
event kernel app sleep on ppp ports auth-req ------> queue auth wake app process auth via PAM etc send ok to kernel tell hw auth-ok <----
