Worked great from clean install.

Note: This notebook has a Radeon Mobility 7500.
This is an 'in-between' gpu, part R100, Part R200.
The ATI Propriety driver will not support this chip.
For full 3D support, you have to build and install DRI.
Instructions here: http://dri.freedesktop.org/wiki/

Note that with a clean install of Kubuntu, there were many packages that the DRI instructions leave out, which I had to add, one here, one there. It took several tries, but I was finally able to complete all the tasks, and tested with a linux-based install of Neverwinter Nights. Ran Great!
