From 73816949f2a28a0b8fe39108a8e493f9e47f7718 Mon Sep 17 00:00:00 2001
From: Egbert Eich <eich@suse.de>
Date: Fri, 28 Jan 2005 16:12:59 +0000
Subject: Modifying X.Org Xserver DDX to allow to run X with ordinary user    
 permissions when no access to HW registers is required. For API changes    
 which mostly involve the modifications to make the RRFunc (introduced    
 with 6.8) more flexible please check Bugzilla #2407. NOTE: This patch    
 applies changes to OS specific files for other OSes which I cannot     test.
