unity 3d should be blacklisted for old graphic card

[Matteo Pagliazzi]

i have a very poor nvidia geforce 7100 with 256mb of memory: it has 3d accelleration that works also with open source drivers so it open unity 3d but now it's unusable so it think that you should blacklist card like mine so that no one can have problem.

With natty it is usable well not perfectly but well
