No, it is not. The GeForce 7 family is the NV40 family, and your specific card 
appears to be NV4B. Refer to


for details.

I doubt. For the general review about what is supported by Nouveau for the 
NV40 family (and other families), refer to the Nouveau feature matrix, at


However, I am not sure how much of the current driver's functionality is 
actually present in the kernel module that comes with CentOS. You didn't 
specify which version of CentOS you use, but at best (CentOS 6.x) the kernel 
is from Fedora 12 timeframe. I am not familiar if all the features and bugfixes 
that have been introduced to Nouveau since that time are actually backported 
to the CentOS kernel. Not sure if it is even possible. YMMV.

If you absolutely need 3D acceleration, maybe take a look at the nvidia 
proprietary drivers --- you can find CentOS-packaged yum-installable rpm's in 
elrepo (or was it rpmforge?)...

HTH, :-)
