ATI Propietary driver install in Debian Wheezy (Xorg downgrade to a working previous version)
Hi all: Searching in the Internet I've found a way to make ATI propietary driver work under Wheezy. Of course, it implies to downgrade Xserver to a version prior to 1.12.
Now I can wait fglrx 12-5 (wich is supposed to work under the new XOrg.

1-First, you must add the repos to dowgrade Xorg
deb http://snapshot.debian.org/archive/debian/20120515T220710Z/ wheezy main
deb-src http://snapshot.debian.org/archive/debian/20120515T220710Z/ wheezy main

2-Create the file /etc/apt/preferences.d/60xorg_rollback.pref
Pin: origin "snapshot.debian.org"
This makes the priority of "snapshot.debian.org" repos for xserver-xorg package higher than any other, so it will install the version desired
3- In order to prevent apt check the date in the repos (this mechanism prevents accidental installation of older software), we create a file called /etc/apt/apt.conf.d/60ignore_repo_date_check
4- We make the changes and downgrade xserver-xorg package
# apt-get update
# apt-get dist-upgrade
5- Finally, download the ati propietary driver from http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx and run
# sh ./amd-driver-installer-12-4-x86.x86_64.run
If you don't have your kernel headers installed, you will need to install them with the good old
# aptitude install linux-headers-$(uname -r)
If the driver doesn't compile properly, you can have a look at /usr/share/ati/fglrx-install.log
If you still have problems with kernel dependencies, the "rude" way to install all necessary packages is
