The monitor section of CRT2 screen is created by basically memcpy'ing primary screen to CRT2 screen, which initially has user defined and default modes in monitor->modes. However CRT2pScrn->monitor->Last is not updated to reflect the new last mode created for CRT2. Since EDID modes are appended to modes pointed to by monitor->Last, they are not added.
