Hello Everyone,
Adding iommu=soft to my kernel line did not help.  (Well directly it didn't.  
Indirectly...)  That gave me the idea to go into my BIOS and disable the 
(Under Advanced Chipset Options):
Intel VT-d
Intel I/OAT

(Under Processor & Clock Options):
Intel(R) Virtualization Tech

I then rebooted, and now the nVidia driver works on my system!  So, is there a 
regression somewhere with the way that Fedora deals with virtualization 
technologies that are a part of the processor itself?  If anyone knows of a bug 
that fits the scenario laid out in this thread, including the changes that I made 
that allowed it all to work again, please let me know.  If not, tell me exactly 
what component a bug should be filed against.

Thanks to all of you for your help!

P.S.: I intend on playing around with my BIOS in the near future to see if I 
really need to have all three of those options disabled.
