+
+    MGA DDX: make it possible to find EXA support
+    
+    Newer versions of the xserver stricter requirements on header order
+    which caused the configure tests for EXA support to erroneously fail.
+    Since XAA was already removed from an earlier version of xserver, the
+    configure failure meant no acceleration was possible. Patch configure
+    tests similar to r128.
