The only thing I can think off might be the output polling task, or the fix from Jerome for AGP suspend/resume 10b06122afcc78468bd1d009633cb71e528acdc5 is AGP one to test disabling output polling is a messier revert, might be easier to just edit drivers/gpu/drm/drm_crtc_helper.c:drm_kms_helper_poll_init and remove the delayed_slow_work_enqueue call, also forcing repoll to false inside output_poll_execute which should in theory stop the polling from starting or being kicked off later. I'll try and recreate if I get a chance, cc'ing dri-devel also for Alex/Jerome.
