 In summary, the nvidia drivers increase the htotal of the accepted
 modeline to ensure it is divisible by 8. This changes the calculated
 refresh rate and can lower it below the 2* framerate threshold needed for
 bob etc.

 The attached patch adds a little tolerance to the accept/reject decision
 to ensure the best deinterlacing options can still be used.

 I'm seeing this on several frontends where the EDID reported timings for
 50Hz modelines give a refresh rate of 50Hz exactly, but by the time the
 drivers have adjusted the modeline the refresh rate drops to circa 49.9Hz.
