Drivers for pretty much everything be availble out of the box and should work without intervention. You will know if a piece of hardware needs attention because it will not function properly - a webcam that does not work, for example. When you encounter these issues, it would be best to open a new question, or seek support on another Fedora support venue from http://fedoraproject.org/wiki/Communicatingandgetting_help .
