Without having any new ATI hardware to test with here myself, I can't be sure of whats going on. All I can suggest is to attempt to re-install fglrx-kernel-source, as well as installing the linux-headers-rt package, which should allow the kernel module for the ATI drivers to be built.

The project's home page is here:
You may need to download build this yourself.
Of particular interest is this section:
This driver is very much a moving target. It looks promising but I am
holding off. Right now the only video device that I will buy is an
Intel. It may not have anywhere near the performance of the ATI and
Nvidia offerings, but it has a proper upstream driver, which for me is
far more important. I do not have any of the supported hardware so I
cannot be of more use.

I had heard that Intrepid had a version of radeonhd shipping with it. I
do not know which version they shipped or how well it works. Given the
pace of development, i would guess that the Intrepid driver is already
For the record, there are two 3d drivers for ATI hardware. There is the
classic binary blob called fglrx. This is the propritary driver and it
supports older ATI hardware as well. The newer radeonhd driver only
supports the latest ATI devices but it is open source, much like the
Intel driver. Check the radeonhd site for more info.
