+Subject: [PATCH] i945/gma.c: generate fake VBT
+
+This generates a fake VBT for the Intel i945 graphic device.
+i945 supports both the mobile chipset 945gm (calistoga)
+and the desktop chipset 945gc (lakeport),
+which is why a VBT with a different id string
+needs to be created for each target.
+
+The VBT id string is obtained from the vbios blob in the following way:
+"strings vbios.bin | grep VBT".
