<pre>Yeah, I think this one here is wontfix since we've intentionally stopped adding
tons of modes - they've actually been added wrongly in some cases:
commit 740922ee575f8ee4daa2bfd3db5f69dd7573fc76
Author: Paulo Zanoni <<a href="mailto:paulo.r.zanoni@intel.com">paulo.r.zanoni@intel.com</a>>
Date: Fri Feb 15 13:36:27 2013 -0200
drm: don't add inferred modes for monitors that don't support them
commit 196e077dc165a307efbd9e7569f81bbdbcf18f65 upstream.
If bit 0 of the features byte (0x18) is set to 0, then, according to
the EDID spec, "the display is non-continuous frequency (multi-mode)
and is only specified to accept the video timing formats that are
listed in Base EDID and certain Extension Blocks".
For more information, please see the EDID spec, check the notes of the
table that explains the "Feature Support" byte (18h) and also the
notes on the tables of the section that explains "Display Range Limits
& Additional Timing Description Definition (tag #FDh)".
