Log message:
Privilege separation for X. This creates a child process in the X server
that keeps root privileges in order to do the few operations that really
need root to work correctly : sending SIGUSR1 to xdm and (re)opening the
mouse device after each VT switch.
It will fix problems with xdm and multiple VTs and kdm too.
Based on some basic code by espie@, provos@ and other contributions.
