I got TSL to run on my laptop which has the previous mobile 965 chipset and X3100 GPU.

People have had a lot of problems getting it to run on that particular chipset, though.
Just follow the directions in the second post of this thread.

Fix their home team score on the board to the debt clock, they can win every game 17,000,000,000,000 to 24. Losing team gets taxed by the IRS 100%, then droned."
