You see, I don't use Fedora anymore so it's a little hard for me to help you. Basically you have to do 2 things. Check if you have all necesssary dependencies, which you should have, because Intel drivers for Linux are open source drivers (Fedora by default doesn't have proprietary drivers) and check if your xorg.conf is properly configured and Intel module/driver is loaded.
Post the output of xorg.conf and check X log files for errors. Try to run;
As they say;
The Xserver is capable of creating its own configuration file. As root just run: X -configure. The Xserver will then load each driver module, probe for the driver and create a configuration file. The configuration file will be stored in the home directory of the user who started the Xserver (usually /root). It's called xorg.conf.new so another config file that may exist in this directory will be overwritten.
Check if libdrm
is installed, it should be version 2.4.0. I guess that newest versions should work too with the version of the driver that you have. You need DRM and AGPGART kernel modules.
./autogen is used for building the driver and if you have it installed with all dependencies you don't need to use it.

I guess that you could visit http://www.x.org/wiki/Home
