As you can see I am a

to Linux myself, I have only installed graphics accelerators on a 3 machines, one on debian and two on SuSE, the only one that I used the fglrx driver for has an ATI 9800 Pro sat in it.
As I am a registered owner of ATI products I got in touch with them to find out if they had drivers for my 7200, I got what would seem to be the standard unhelpfull e-mail to my query, basically stating that they don't have a propietry driver for this card and that they don't release thier drivers code to the open source community, but that they are willing to help if I was to try and develop a driver myself.
After that little bombshell they suggested looking on the DRI project and MESA, so that is where I went to get the driver for my card.
Don't get me wrong I would love to develop a driver for my card, but I am probably the worlds largest coding numpty so the chances are better that I develop a set of wings and fly to the moon in the next couple of minutes.
