I replaced the radeonhd driver with the radeon driver in
/etc/X11/xorg.conf after installing x11-drivers/xf86-video-ati, but
that driver doesn't even find my screen.

from the modified xorg.conf :

Section "Device"
  Identifier "* Radeon"
  Driver "radeon"
  BusID "pc:1:0:0"
  Option "DRI" "true"
  Option "ForceDPI" "98"
EndSection

Section "Screen"
  Identifier "Screen 1"
  Device "* Radeon"
EndSection
