Those drivers are leaked, So you are really not suposed to use them. If you do, you do it on your own risk.
I _think_ you can fix the Ff8 problem with RivaTuner, Install it and dissable 8bit palettized textures under Dx7 applications. Im alittle un sure about the fix as it was some time a go I red about it. But I know it was something along those lines.
