is it working in any nvidia cards or only the gtx 750 ti ?
Also what is the size of the image ?
I didn't check it, but it should work properly with other Nvidia cards, cause the driver is 334.21 linux 64bit:
http://www.nvidia.com/Download/driverResults.aspx/73666/en-usI set image size 7700MB, just to fit into any kind of 8GB pendrive
after zip compresion - about 3GB
