Yup, this is an issue and nvidia is aware of it though they don't have
a viable solution yet.  They were able to reproduce it and have a
workaround but I've not tried it.  See the forum for details:

https://devtalk.nvidia.com/default/topic/898310/linux/352-63-regression-quot-noedidmodes-quot-breaks-custom-quot-modeline-quot-modes-ubuntu-14-04-/

I found that I was able to get the 340.98 drivers to work
correctly....  nothing after that.  Fortunately this was able to be
install on a 4.8.0 kernel.  Until Nvidia has a true fix I'll stay with
this driver.
