Glad to see some NVIDIA folks in this forum who don't specifically stick to the Linux section. I sincerely hope that if/when this whole rolling lines/flickering business is resolved that Brian and anybody else from the company decides to hang around here, we'd love to have you.
I have to RMA an Albatron 5900PV. It was not experiencing this problem, but there are some severe power management issues with this card. As soon as the card comes back I will test it and you'll be the first to know if it exhibits this behavior.
