- vesa-1.2.1-validmode.patch: Strictly limit runtime modes to the
        intersection of the BIOS and DDC lists, if a DDC list exists; fixes
        cases where we'd choose 1600x1200 on 1680x1050 panel. Conversely, be
        more forgiving when validating the resulting set against the sync
        ranges; fixes 640x480 syndrome when the monitor has broken DDC. Don't
        be deceived though, vesa still sucks.
