nvidia handholding

Ok, so I made the switch to nvidia, 6600GT. Now what? Following the instructions on the nvidia website I used YOU to install the patch and all seemed to go well there. It then said, "...logout, login back in and you're fine..." Apparently not. Check with SAX2 still shows card as VESA framebuffer device. I tried deleting that and specifying the 6600GT card and got some hiccups and a big burp. Lost the X system. Is there something else I need to do to get the card recognized and running? Should I follow the X configure step listed even though the site seemed to think this would be done already? Sorry. I am a babe in the woods here. Richard
