For login time stuff pam has the needed framework for the general case
(Posix like file systems) - there is no suid on some others and SELinux
makes it more fun. Right now pam handles console login permissions for
stuff like audio on login, but doesn't really look at X stuff.

For startx its harder because X may not be suid I guess ?
