--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
Of course, that commit is just the icing on the case. After Egbert's patch, we
successfully read the EDID for the SDVO panel and then things go wrong...

Before:
[    0.610486] [drm:drm_helper_probe_single_connector_modes],
[CONNECTOR:15:LVDS-2] probed modes :
[    0.610490] [drm:drm_mode_debug_printmodeline], Modeline 17:"1024x600" 60
50500 1024 1034 1066 1348 600 612 616 624 0x48 0xa

After:
[    0.653730] [drm:drm_helper_probe_single_connector_modes],
[CONNECTOR:15:LVDS-2] probed modes :
[    0.653733] [drm:drm_mode_debug_printmodeline], Modeline 18:"1024x600" 60
44700 1024 1034 1066 1194 600 612 616 624 0x48 0xa
[    0.653739] [drm:drm_mode_debug_printmodeline], Modeline 19:"1024x600" 40
29800 1024 1034 1066 1194 600 612 616 624 0x40 0xa

And then there is an even greater discrepancy in the adjusted modes for the
first modeset:

Before:
[    1.110223] [drm:intel_dump_pipe_config], adjusted mode:
[    1.110228] [drm:drm_mode_debug_printmodeline], Modeline 0:"1024x600" 60
101000 1024 1034 1066 1348 600 612 616 624 0x48 0xa

After:
[    1.186459] [drm:intel_dump_pipe_config], adjusted mode:
[    1.186463] [drm:drm_mode_debug_printmodeline], Modeline 0:"1024x600" 60
178800 1024 1034 1066 1194 600 612 616 624 0x48 0xa


Before we have a pixel multiplier of about 2, and afterwards closer to 4.
