libwfb.so not installed with nvidia driver

Binary package hint: nvidia-glx-new

After installing my new Geforce 8800 GTS, the XServer did not start with the nvidia driver and exits with this error message:

...
(II) Loading extension NV-GLX
(II) NVIDIA(0): NVIDIA 3D Acceleration Architecture Initialized
(EE) NVIDIA(0): Need libwfb but wfbScreenInit not found

Fatal server error:
AddScreen/ScreenInit failed for driver 0
---

To resolve this problem, the following steps had to be done (found solution in forums around the web):
- Download nVidia installer 1.0-9755
- Extract with '-x' option
- copy and or link
  NVIDIA-Linux-x86-1.0-9755-pkg1/usr/X11R6/lib/modules/libnvidia-wfb.so.1.0.9755
  to /usr/lib/xorg/modules/libwfb.so

Be aware, that the problem only occurred with the new 8800 card. My old 6800 worked perfectly without this library.
