Thanks, yes I think you're right. Also, 3137 and 49827 are probably related.
One thing you could try is installing displayconfig-gtk and see if you can set up the resolutions using that tool.
Otherwise, the workaround is to hand-edit your xorg.conf to add in the missing resolution (and add/fix/remove the refresh rates as needed).
