You have to recompile ATI FGLRX drivers to properly work on your card as I Did. But by now I cannot remember where I found the instructions to do.
It functions Very well. Oh, do not forget to update all of your system before do it.
I've found it only in portuguese, then I tried to translate this friend's site post.

Thanks for Thiago Augusto for this tutorial ( AKA Luminance )
Do this ( Valid for AMD 64 )
1. Edit : linux-restricted-modules-common
$ sudo gedit /etc/default/linux-restricted-modules-common
Find the Line : DISABLED_MODULES=?"
And Leave : DISABLED_MODULES=?fglrx?
2. Installing the New driver
Download the driver from ATI
32bits -> ati-driver-installer-8.29.6.run
64bits -> ati-driver-installer-8.29.6.run
Enable the Universe and Multiverse on your repositories under your package manager.
$ sudo apt-get update
Installing necessary things to recompile:
$ sudo apt-get install module-assistant build-essential
$ sudo apt-get install fakeroot dh-make debconf libstdc++5 linux-headers-$(uname -r)
3. Generating .deb packages
Go to the directory that you have downloaded the .run package
Execute the .run package :
sudo $ bash ati-driver-installer-8.29.6.run --buildpkg Ubuntu/dapper
4. Installing the .deb generated
$ sudo dpkg -i xorg-driver-fglrx_8.29.6-1_i386.deb
$ sudo dpkg -i fglrx-kernel-source_8.29.6-1_i386.deb
$ sudo dpkg -i fglrx-control_8.29.6-1_i386.deb
5. Removing the older packages .deb out of fglrx in /usr******/
$ sudo rm /usr******/fglrx-kernel*.deb
6. Compiling the new kernel module
$ sudo module-assistant prepare
$ sudo module-assistant update
$ sudo module-assistant build fglrx
$ sudo module-assistant install fglrx
$ sudo depmod -a
Note: If you did an update to your kernel, you have to redo the step 6
7. Updating xorg.conf
$ sudo aticonfig --initial
$ sudo aticonfig --overlay-type=Xv
8. Reboot
$ sudo reboot -h now
9. Verifying if evrything is OK
type fglrxinfo on the command prompt
If this appear:
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON XPRESS Series Generic
OpenGL version string: 2.0.6065 (8.29.6)
Everything is OK !
Thanks for use Linux, our beloved O.S.
