Here's the PROPER fix to this issue:
The issue with these laptops is not caused by the GT 330M GPU, but is instead the fault of a poly-tantalum capacitor near the CPU that supplies power to the GPU's frame buffer. Poly-tantalum capacitors are quite unreliable, and when this capacitor intermittently fails, the voltage to the GPU drops, and it causes a kernel panic. The thing is, heating the board in an oven or reflowing the GPU will temporarily fix this issue by indirectly heating the capacitor, as capacitors are known to sorta fix themselves when heated up.
Therefore, you can permanently fix this issue by replacing the affected capacitor, a 330µF 2.0V called "C9560" with another capacitor that isn't a tantalum one.
I recently fixed a laptop with this issue by replacing C9560, and it would die after 5 minutes of running Furmark. After replacing the capacitor, it has been running the same program for over 5 hours with no issues!
