As Jesse said, the problem is definitely that you don't have openGL working on your system.

If you run "glxinfo |grep render" I'm sure that it will say "No" to "Direct Rendering". Does that driver come from ATI? I've never used their binary drivers but I have a 9250 128M PCI (R200 chipset) right now and it works fine with just the kernel module. I'm not sure how easy FC4 makes it get at the kernel source. And chances are that the module is already built. Also you need to make sure that /etc/X11/xorg.conf knows about your card and how to use it. Mine looks like this;

Section "Device"
    Identifier  "videocard0"
    Driver      "radeon"
EndSection

If the ATI driver is just called something a little different, it may just be a matter of changing the "Driver" to that. Helpful information can be found in /var/log/Xorg.0.log (Is there an error? Did the driver load? etc...).

There is a whole agenda with getting 3d working. AGP support and mobo chipset support needs to be enabled. Most of the newer distros (like FC4) have all of this configured though. I'm kind of surprised that fc4 didn't pick up on it and get it working. Did you add the card *after* your initial installation?

Here's some ATI driver stuff that could help.

Let us know how it goes.
