 *     @default_mode fails, all modes in the video mode database will
 *     be tried.
 *
 *     Valid mode specifiers for @mode_option:

 *      If 'M' is present after yres (and before refresh/bpp if present),
 *      the function will compute the timings using VESA(tm) Coordinated
 *      Video Timings (CVT).  If 'R' is present after 'M', will compute with
 *      reduced blanking (for flatpanels).  If 'i' is present, compute
 *      interlaced mode.  If 'm' is present, add margins equal to 1.8%
 *      of xres rounded down to 8 pixels, and 1.8% of yres. The char
 *      'i' and 'm' must be after 'M' and 'R'. Example:
 *
 *      1024x768MR-8@60m - Reduced blank with margins at 60Hz.
 *
 *     NOTE: The passed struct @var is _not_ cleared!  This allows you
 *     to supply values for e.g. the grayscale and accel_flags fields.
 *
 *     Returns zero for failure, 1 if using specified @mode_option,
 *     2 if using specified @mode_option with an ignored refresh rate,
 *     3 if default mode is used, 4 if fall back to any valid mode.
