The wait is over! A working patch has been posted on http://ati.cchtml.com/show_bug.cgi?id=495 by Zenitur.
HINT: /dev/shm makes a nice ramdisk if you have >2GB RAM.
Latest: Alberto Milone has pushed an updated 9.860 that has support for kernels 3.4 and 3.5: https://launchpad.net/ubuntu/quantal/+source/fglrx-installer/2:8.960-0ubuntu2 (3.5 support nor working for me, locks as X loads).
Latest beta: Catalyst 12.6 Beta works. Instructions below. If unsure use 12.4. Thanks to miatawnt2b for pointing out the 12.6 beta existed!
In summary: 0) Preparation 1) Download and extract 12.6 from AMD. 2) Apply the patch attached [URL="http://ati.cchtml.com/attachment.cgi?id=464"]here. [/URL] 3) Build packages 4) Install 5) Remove watermark
Details: 0) If this is the first time you've done this, install the necessary development packages (normally installed by the installer, if any are missing they will be identified in step 3): $ sudo apt-get install dpkg-dev debhelper dh-modaliases execstack
1) Once downloaded (the .run is in a .zip file. I shouldn't have to tell you how to deal with that), extract the installer files so we can patch manually: $ sh ./amd-driver-installer-12-4-x86.x86_64.run --extract ~/temp/amd
2) Download and apply the attached patch (taken from Arch's catalyst-test):[URL="http://ati.cchtml.com/attachment.cgi?id=464"] [/URL]$ cd ~/temp/amd $ patch -p1 <./3.4.patch
3) Build the packages (this will place the packages in the parent directory): $ ./ati-installer.sh 8.980 --buildpkg Ubuntu/quantal
4) Change to the parent directory and install the debs: $ cd .. $ sudo dpkg -i *.deb
5) In order to remove the watermark you will need to add a signature to /etc/ati/signature . I took the signature from 12.4 as demonstrated here: http://wiki.cchtml.com/index.php/Amd_watermark
All you have to do is add the following to /etc/ati/signature and restart X (e.g. log out).

$ sudo aticonfig --initial and reboot.
All should work!
