First of all, you'd check whether it's installed or not:
$ sudo rpm -q xorg-x11-drv-intel
If that's the output, then you'll have to check for other issues in your config. Anyway, if the rpm command doesn't show anything for installing it, the easiest way is using yum for downloading it from online repos:
$ sudo yum install xorg-x11-drv-intel
Once installed restart you're X server or simply reboot your machine. After the reboot, if resolution is not good check it on Gnome display settings, you'll find it on "Applications -> System settings".
I have to say I've been using Fedora 17 and Kororaa (a Fedora 17 remix) with the same graphic card you've got and had no problem, the driver was installed during installation process and had nothing else for configuring.
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
BTW, if you still have problems after checking everything, could you please provide more information about your setup ? Desktop environment, type of installation you did, are you using official Fedora or a Remix?...and so on. Thanks.
