+From: Arthur Heymans <arthur@aheymans.xyz>
+Date: Sun, 15 May 2016 02:17:12 +0200
+Subject: [PATCH] i945: Enable changing VRAM size
+
+On i945 the vram size was the default 8mb. It was also possible
+to set it 1mb hardcoding it in early_init.c
+
+The intel documentation on i945 only mentions those two options.
+It was set using 3 bits. The documententation also makes mention
+of 4mb, 16mb, 32mb, 64mb but not how to set it.
+
+Other non documented (straight forward) bit combinations allows
+to change the VRAM size to those other states.
