Just to add for clarity, it shouldn't be surprising that I had to remove:

hw/xfree86/modes/xf86Crtc.c:

handle_detailed_physical_size() ...
      p->output->mm_width = det_mon->section.d_timings.h_size;
      p->output->mm_height = det_mon->section.d_timings.v_size;

since it seems to be called on each DDC probe and not just when the connected output device has changed. This should at least be conditional on DisplaySize not being set.

I don't think this has really been noticed since the core DPI is no longer tied to the output size/resolution, but any app wanting to make use of the actual display characteristics via randr will potentially get some very wrong values!
