As someone else mentioned in the thread, your chipset is not poulsbo, I don't know whether this is the right solution but nonetheless the non-free drivers are called xorg-x11-drv-psb. So enabling the RPMFusion repositories, both free and non-free and then a yum install should let you install them.
I'm confused, you confirmed those aren't applicable to his chipset but suggest he use them? Ok...
CMIIW, but wasn't that yanked out before F13?
