How to switch to a particular resolution? Xorg complains "No valid modes for "DFP-1:2560x1600"; removing." and ignores my setting.

Adding this line

into the "Device" section didn't help, and Xorg printed the same warning

There are sections for all depths, including Depth 24, so this isn't a 
problem.
