Hey Albert that hing with rivafb i thinks thats no problem, i get that message as well, that means ther kernel you've got in your system has support for rivafb but as long as the module isn't loaded there's no problem... I'm using SlackWare 10 and i get thet error about not loading nvidia.ko and kernel sources problem so i think nvidia should have a look at this since it's not a one problem distro. I'm going to send them guys an e-mail to ask for support, i encourage you guys to od the same

btw when you get your replies from the nvidia guys it would be good to post them here . Cya
