update, i changed the patch to do a printf() instead of DRM_ERROR as i mentioned in the last message. instead of printing an error it just says the edid is empty:
inteldrm0 at vga1 drm0 at inteldrm0 drm: EDID is empty VGA-1: EDID block 0 invalid. inteldrm0: 1024x768 rather than: > inteldrm0 at vga1 > drm0 at inteldrm0 > error: [drm:pid0:drm_edid_block_valid] *ERROR* EDID is empty > VGA-1: EDID block 0 invalid. > inteldrm0: 1024x768 which looks much nicer (and more accurately reflects the situation). new patch and dmesg at end.
