The only way I know how to update the cards listed in XFdrake is by upgrading to a newer version. If yanc is saying that there is no driver, then it probably isn't installed correctly. You might try re-installing. Follow the instructions carefully on the Nvidia README. I don't know what else to suggest. Good luck
For your reference, here is my working config file:
