Same Problem here. You can use the following work-around
1. mkdir [KERNEL-FIRMWARE-DIRECTORY]/edid
2. cp [MONITOR-EDID-FILE].bin [KERNEL-FIRMWARE-DIRECTORY]/edid
3. add the following to your Kernel Commandline:

drm_kms_helper.edid_firmware=edid/[MONITOR-EDID-FILE].bin

This will provide kms and Friends with correct EDID-Informations. However
to stop the annoying flicker, you have to 
4. add another Statement to your Kernel Commandline:

drm_kms_helper.poll=0
