I just installed Kubuntu 8.04.1 AMD64 and had the same problem except it was the nvidia-glx package, not nvidia-glx-new. The package was partially installed and I was unable to install or remove any of the nvidia packages. nvidia-glx was complaining about "/usr/lib32/libGL.so.1 does not exist", same as Chuck.
I was able to get this working by creating "/usr/lib32" which did not exist.
sudo mkdir /usr/lib32
After that I was able to uninstall/reinstall nvidia-glx and install the other nvidia packages.
Looks like something needs to be fixed in the nvidia packages for AMD64 to correct this issue.
