+	  X.Org driver for iMX6 GPU (Vivante)
+
+	  Notice EGL and GLes2 APIs are correctly supported. This
+	  driver should also be able to provide Desktop OpenGL
+	  implementation but, this feature seems broken since quite
+	  some time.
+
+	  To use this driver, add correct configuration to your
+	  /etc/X11/xorg.conf:
+
+	  Section "Device"
+	    [...]
+	    Driver          "vivante"
+	    Option          "vivante_fbdev" "/dev/fbX"
+	  EndSection
+
+	  Don't forget to load galcore.ko and create /dev/galcore
+	  before using this driver (else, Xorg will exit with an
+	  obscur message like "Segmentation fault at address 0xc").
