*
* If 'M' is present after yres (and before refresh/bpp if present),

* 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.
*
