+EDID has (essentially) three statically defined mode lists: Established,
+Established III, and DMT.  The DMT list is _almost_ a superset of the other
+two, except.
+
+EST slot 0 is DMT slot 8
+EST slot 1 is DMT slot 7
+EST slot 2 is DMT slot 5
+EST slot 3 is DMT slot 4
+EST slot 5 is DMT slot 3
+EST slot 8 is DMT slot 35
+EST slot 9 is DMT slot 17
+EST slot 10 is DMT slot 16
+EST slot 11 is DMT slot 15
+EST slot 12 is DMT slot 14
+EST slot 14 is DMT slot 10
+EST slot 15 is DMT slot 9
+EST slot 16 is DMT slot 20
+
+EST slots 4, 6, 7, 13 are:
+640x480 @ 67HZ
+720x400 @ 88Hz
+720x400 @ 70Hz
+832x624 @ 75Hz
+
+Everything in EST3 is in DMT, except for slot 35 (1792x1344 @ 85Hz).  Strong
+work, VESA.
+
+DisplayID, however, encodes the DMT list indexes directly.  So if you built
+a unified list for DMT+EDIDextras and indexed into that, you'd have to do so
+for DisplayID too (probably not 1:1).
+
+This is really pure optimization.  Each mode is only 60 (or 64) bytes as it
+is.  So you're going from 64 * (17 + 44 + 80) = 9024 for three lists, to
+64 * 85 + (17 + 44 + 80) = 5581 for one master list and three indices.
+Kinda tough to care about one page of .rodata.
