Yeah, that's what troubles me. My current Thinkpad has NVidia and is working reasonably well using the proprietary drivers, but I know support has been hit or miss over the years with various chips. There was a time when I was unable to upgrade my OS for several years until I decided to get a new laptop, because the updated driver dropped support for my chip, and the old driver wouldn't work with the updated OS.
