I would suggest you look at the 'libpam-devperm' package.  Here's what 
the description says:

PAM module to change device ownership on login
This PAM module allows you to change device ownership and permissions
when a user logs in.

This is functionally equivalent with SunOS logindevperm(4).

I used this a while ago to setup ownership of devices for users who 
logged in to X (runlevel 5) using gdm.
