0. patch your system up to kernel-2.6.29.1-54.fc11 and
  xorg-x11-drv-ati-6.12.1-10.fc11 . Those are available from koji :
  http://koji.fedoraproject.org/koji/buildinfo?buildID=97202
  http://koji.fedoraproject.org/koji/buildinfo?buildID=96839
1. rename xorg.conf to xorg.conf-backup
2. check grub.conf for "nomodeset" and remove it as needed (a backup
  of the original grub.conf is advisable as well)
3. reboot.

You should be using the radeon driver in KMS mode.

If that fails, boot without KMS (add  nomodeset  to the kernel command
line). If that still fails, boot into runlevel 3 (add  3  to the kernel
command line) and switch back grub.conf and xorg.conf to the original
state.

If this fails, please file a bug with Xorg.0.log and dmesg from KMS and
non KMS attempts attached (uncompressed, text/plain please).
