No, that would be a security problem -- and it's actually documented in the
pam_group module documentation. If I, as the console user, become even
temporarily a member of the console group, nothing prevents me from
creating a setgid binary which will give me the group membership later,
when I'm not on the console anymore.
The chown-ing on console login (or some similar method through devfs/devfsd)
is the cleanest way to do this.
