Does "kldload radeonkms" as root work, as in gives you a nice looking 
console in native screen resolution? If that works, at least the KMS 
driver does something correctly.

Another idea is to try to rebuild the "x11-drivers/xf86-video-ati" port, 
if you haven't done that already.

Can you post the complete contents of /var/log/Xorg.0.log and the output 
of dmesg after a failed attempt to start the X server?
