Today I tried it by emerging nvidia-kernel-1.0.8178-r3 and 
nvidia-glx-1.0.8178,
having gentoo-kernel 2.6.14-r5 running. Loading the kernel-module with 
modprobe
works fine. Than I tuned my xorg.conf to use the nvidia-glx module, now 
my xorg.conf
looks like this:

Starting up xorg just with 'startx' works fine.. xfce4 comes up. But 
lateron it hangs with nearly 100 percent of cpu-time usage,
especially if I use the webbrowser firefox.

I don't know what's wrong. Any more hints on that?

thx,
Jonatan
