As you have seen before the kernel include files for the Knoppix 7.2.0 kernel are present on the CD edition otherwise you would not have been able to compile and install the current driver from the experimental repository.

The driver you found at NVIDIA's website is many years old. There were many improvements and changes in the kernel include files since then. Therefore I would not expect the old driver to be compatible with today's Linux kernels.

It is possible to execute the .run file with the option '--help' or '-h -A'. This will show you a list of options you could try out. Since it is a long list you should use an LXTerminal with scroll bars.
