+Subject: [PATCH] i945: Enable changing VRAM size
+
+On i945 the vram size was the default 8mb. It was also possible
+to set it 1mb or 0mb hardcoding the GGC register in early_init.c
+
+The intel documentation on i945 only documents those three options.
+They are set using 3 bits. The documententation also makes mention
+of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it.
+
+The other non documented (straight forward) bit combinations allows
+to change the VRAM size to those other states.

+Subject: [PATCH] i945/gma.c use latest linux code to calculate divisors.
+
+The code to compute n, m1, m2, p1 divisors is not correct in coreboot and
+on some targets hits a working mode at lower refresh rate, which is why
+display is working on some targets.
+This patch also fixes reference frequency.
+
+This patch reuses linux code to correctly compute divisors.
+
+The result is that some previously not working displays (Lenovo T60 with
+1024x786, 1400x1050, 2048x1536)
+
+TESTED on T60 with 1024x786.
