+From 894680ec0335d7bc2c744c53f6a28b40ab850b6c Mon Sep 17 00:00:00 2001
+From: Keith Packard <keithp@keithp.com>
+Date: Mon, 28 Sep 2009 12:39:47 -0700
+Subject: [PATCH] Re-fix DGA removal.
+
+Removing DGA ended up breaking any drivers calling into the old
+xf86DiDGAInit function as it tried to see if DGA was already enabled
+and ended up crashing if the VT wasn't completely initialized. Oops.
+
+Also, if the driver initializes DGA itself, have the DiDGA
+initialization overwrite that information as the DiDGA code will call
+ReInit on mode detect.
+
