can you install Fedora 17 on it as well, when you choose basic graphics driver mode?
it's likely that the free Radeon driver has support for your card, if you update the kernel to 3.4.5-x (or even kernel-3.5.x
, even though it is not finished yet). There are packages for this kernel in Fedora 17 and maybe under F16 as well.
yum update kernel
maybe it helps. You can also update mesa* and xorg-x11* (but probably the kernel update is the essential part)
yum update mesa* xorg-x11*
then reboot to the new kernel to see if it works. If not, you could also follow this guide: leighs guide
But if the default driver works for you, I wouldn't mess with it. Only if you really need better 3D acceleration or better power saving.
you could also check the file /boot/grub2/grub.cfg
below the entry for Fedora, check the line where it says "linux /boot/vmlinuz...."
in this line there should not be nomodeset and not radeon.modeset=0, radeon shouldn't be blacklisted.
