Maybe, maybe not.  I doubt that it's as easy as flipping a switch.  First, 
you need to install ATI's non-free kernel driver.  It's not a part of Fedora 
because it is not free software.  And it won't magically appear out of 
nowhere.  You have to install it, and it likely needs to be compiled for the 
kernel version you're running.  Anytime you update the kernel in the future, 
you will need to recompile it again.

I do not know if there's a prepackaged ati driver that you can install from 
some third-party yum repository.  I can't find it in Livna, the usual place 
for these kinds of things.  I have not looked at ATI's non-free driver, but 
it's fairly likely that its installation instructions is non-trivial. 
Welcome to the world of non-free, proprietary software.

No, it's done by installing Xorg, which includes XGL.
