+    xfree86/modes: Remove all framebuffer support from DGA
+    
+    This removes all rendering and mapping code from xf86DiDGA, leaving
+    just mode setting and raw input device access. The mapping code didn't
+    have the offset within /dev/mem for the frame buffer and the pixmap
+    support assumed that the framebuffer was never reallocated.

+
+    Add configuration option for use of SIGIO handlers for input events
+    
+    Boolean option to enable/disable SIGIO handlers is set by the first
+    of these found:
+      - UseSIGIO option is set in xorg.conf ServerFlags
+      - Default set at build time by ./configure --enable-use-sigio-by-default
+      - Platform default value: Solaris = no, all others = yes
+    
+    This matches the current settings on all platforms except Solaris.
+    This reverts Solaris (for now) to the settings used in Xorg 1.6, before
+    SIGIO support for Solaris was added, due to some system level bugs that
+    won't be resolved in time for Xorg 1.7 release, but allows us to enable
+    when those are resolved (or when we need to test if they're resolved).
+    See http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6879897

+    dix: append "built-ins" to the font path in SetDefaultFontPath
+    
+    49b93df8a3002db7196aa3fc1fd8dca1c12a55d6 made the hard dependency on
+    a "fixed" font go away but only Xorg could use the built-ins fonts by
+    default.
+    
+    With this commit, all DDXs get "built-ins" appended to their FontPath, not
+    just Xorg.
+    
+    Tested with Xorg, Xvfb and Xnest.

+    Fix num_masks/length overflow test for XiSelectEvents
+    
+    Have to set windowid to a valid value first, since that check
+    appears earlier in the code than the masks/length check.
+    
+    Also have to have data[] set large enough so that reading mask

+    into uninitialized data.
