Dell Precision T3400n and nVidia Quadro FX 570 dell driver

I have a Dell Precision T3400N desktop with an nVidia Quadro FX570 video card. I tried to install the nVidia drive from Dell labeled.

dell-nvidia-12-1dkms.x86_64.rpm. Whe I triy to do so, I get the following error:
file /usr/bin/ from install of dell-nvidia-12-1dkms.x86_64 conflicts with file from package x11-video-nvidiaG01-173.14.18-19.4.x86_64

Has anyone successfully installed the Dell nVidia driver with Opensuse 11.1? If not which driver should I use from nVidia to get this to work.
