Catalyst 8.2

ATI Catalyst Linux 8.02 driver

Release date: 13 February, 2008

Driver version: 8.455.2

If the graphics card was not in your comutper when you installed the video drivers, then it either didn't install any drivers, or it installed the wrong ones.I would suggest a reinstall, or if you can find a backup version of xorg.conf, which is usually in /etc/X11. The backup would have a long string of numbers, which would translate into a date of when the backup was created. (Example: xorg.conf.20100121_14:21). I could be wrong on the placement of the numbers, but you get the idea.
