 *      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,

 *	3 if default mode is used, 4 if fall back to any valid mode.
