Hey, nVidia, what has happened to your drivers lately? They seem to have all the quality I expect from ATI drivers. I have new problems I didn't have before my last Linux driver upgrade. What, exactly is wrong over there, and what can I do to help short of buying a $600 graphics card from you? Sincerely, formerly a rabid pro-nVidia, anti-AMD Linux user.
Via VT6656 USB WiFi has been out-of-tree because of non-GPLness. The new driver is a candidate for inclusion supposedly but for now you need to build your own driver in most cases. I want it for Debian 5 on my DT360.
Nouveau is an open source project to create a Free driver for nVidia-chipset graphics solutions.
