  following up on an earlier post, the only way i could install f11
beta on a new gateway m-1626 with a 1280x800 display and a radeon
xpress 1270 video chipset was to select "simple video driver."

is there a graphical way to adjust this, or should
i fix this by manually editing xorg.conf?
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.

  done all that, no change.  i first rebooted with the new ati driver,
didn't help.  i rebooted and manually added "nomodeset" to the kernel
command line (and verified it was there via /proc/cmdline), no
difference.  then rebooted normally again, still no change -- stuck at
1024x768.

  this is the relevant snippet from dmesg from that last reboot:
