PAM can be configured to chown tty (and other devices) on login. That
is probably it. If it's not pam, some other part of the login process
has been configured to do so (a non-standard getty or whatever). The
kernel is certainly not doing so (except through chown) -- the kernel
wouldn't even know where to find matching device file(s) in order to
make this change.
