AFAIK the situation has not changed. The rt patch for 3.x.x disables a 
few internal symbols for non-GPL software and then the Nvidia driver 
can't work. I have not heard of workarounds (save for building a kernel 
with the needed patch that turns those symbols back into what they were 

Of course running a normal Fedora kernel should not be a problem if you 
have rpmfusion enabled.
