The message is very clear. Modules must be compiled against the same kernel source that will be 
used, and using the same compiler. In your case, gcc-3.4 was used to compile the kernel and gcc-4.0 
was used to compile ndiswrapper. You have 2 easy choices: (1) If the full kernel sources are 
installed, recompile and reinstall the kernel, or (2) There is a python module that will change the 
version magic in modules. Google for "change version magic module".
