Comment 2 for bug 348262

The only physical card I have and I am using is the GTS 250. I do not have access to other cards. I agree that caution dictates testing the real card.

My main motivation is the out-of-the-box experience for new adopters of Ubuntu who will purchase new PCs. If not having the ids in still allow them to have a desktop and the restricted driver manager offers an alternative, this is good. Same goes for those who upgrade PC with a new card.

Regarding the GTX 200 series:
As for the GTX 200 series, I found evidence on the Ubuntu forum that it works with the nv driver (which surprises me):

All 4 cards in this series have the same new GT200b GPU.

I also found this article:
"This morning NVIDIA had unveiled the GeForce GTX 200 series and already NVIDIA's Aaron Plattner has committed support for these cards to the open-source xf86-video-nv driver. This support just involved adding in two new PCI IDs for the GeForce GTX 260 and GTX 280. No other work was needed, since of course this driver is limited to mode-setting and 2D acceleration."

Regarding the missing ids in the list of existing bugs:
I have not read in details to find if the cards worked or not. I compared the latest nv_driver.c and the nvidia 173 (latest I could find) driver device ids.

This is all the information I can contribute. You analyze the risk, I'll support the decision you make.
Let me know if I can do something else to help.
Thanks
