When I upgraded to Fedora 12, 

I had an error, to the effect, hardware was already in use.
I found the "nouveau" driver had the hardware.
My xorg.conf file was using the "nv" driver.
Not thinking, I changed from the "nv" driver to the "nouveau" driver. 

Searching the Internet, for the words, blacklist nouveau,
I found the following comment at URL:
http://linux.derkeiler.com/Mailing-Lists/Fedora/2010-01/msg02113.html

The summary of the comment was, if you use the rpmfusion repository,
for the nvidia module, it will automatically blacklist nouveau?

If I do an Internet, search for the words, blacklist nouveau nv,
I find indications some people, not sure who, claimed the nouveau
driver has passed up the nv driver, and has been made the default.

Questions please:
1) Are there 3 drivers, nvidia, nv, nouveau?
2) If there are 3 drivers, how did people decide which driver to use?
   My questions on this subject, are as follows:
   a) Is the nouveau driver now considered better than the nv driver?
      If the nouveau driver is considered better, I am curious why?
   b) Is it true the nvidia driver is faster than the nouveau driver?
      I wanted to use the "free" driver, if possible, so I was using nv.
      I switched to nouveau because that seemed to be the new default.
      I am wondering what I am giving up not using the nvidia driver.
