The code in function intel_crtc_compute_config() that evens pipe_src_w if necessary would look at the current config instead of the staged one when deciding if there is an LVDS encoder in use. This could potentially lead to the value not being updated, if during the modeset a crtc wasn't driving an LVDS encoder.
