As a beginner, I thank you for the help, Silent Bob. I was trying to upgrade from a GeForce 3 to a 5700 Ultra, and whatever drivers come with FC1 weren't working. It worked just fine after following those steps.
Well, almost. I had to reverse steps 7 and 8. And, the link you give, which has steps 1-4--those steps didn't work. The packages weren't found at that web address. (Perhaps this is why you didn't list those steps.) But of course the packages are easy enough to find elsewhere.
