I would recommend to use the Debian packages (nvidia-glx etc.) instead.

The reason is that "a driver such as rivafb/nvidiafb is present…",
namely the nouveau module which is new in 2.6.32-5.  You need to
blacklist it (see modprobe.conf(5) and reboot to get rid of it.

If you had used the Debian packages this would not have happened,
because the nvidia-kernel-common package blacklists nouveau for you.
