Kudos.  It works for me on a T30 with a Dell 1703FP monitor running
today's Ubuntu edgy.  Here are the notes I made:

Get:

  cg-clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati
  cd xf86-video-ati
  git-revert 22860a3c0685a25f982983654303ad02aedc02ec

Build:

  ./autogen.sh prefix=/usr
  make

(To build I had to apt-get install these packages:

  xserver-xorg-dev
  xorg-build-macros
  x11proto-xf86misc-dev
  x11proto-gl-dev

Readers may have to install other packages which I happened already
to have installed.)

Install:

  mv /usr/lib/xorg/modules/drivers/radeon_drv.so /usr/lib/xorg/modules/drivers/radeon_drv.so_FACTORY
  cp src/.libs/radeon_drv.so /usr/lib/xorg/modules/drivers
  chmod ugo-x /usr/lib/xorg/modules/drivers

Edit /etc/X11/xorg.conf to add:

  Option "MonitorLayout" "LVDS, TMDS"

to Section "Device" for Driver "radeon".
