According to the Xorg log file, the 1600x1200 mode validated but does not get added to the XRandR/XF86VidMode list. 1600x1200 may be clipped because the virtual screen size is set to 1024x768. According to the xorg.conf man page for the Virtual option: Video modes which are too large for the specified virtual size will be rejected. What happens when you explicitly set the virtual desktop size to 1600x1200 with the Virtual option?
