I've been using an GeForce2 MX400 (from MSI) on Potato and now Woody with XFree86-4.1. It's a great card for the price, the hardware acceleration works well with my OpenGL visualization applicatons based on VTK. I've had no problems. We also have some high end NVidia cards that we use for scientific visualization on Woody boxes that are also fine.
