From c798a382f1e11a0fd60a78924db0663f8e988a1b Mon Sep 17 00:00:00 2001
From: Eric Anholt <anholt@freebsd.org>
Date: Wed, 29 Jun 2005 02:54:19 +0000
Subject: Get the BSD DRM compiling again after MGA and mapping changes. Note
 that     i915 has been disabled for the moment, rather than working around   
  linux-specific code in the shared dir.
