You can have multiple kernel source code, then compile the code. But here you will not able to test it. When compiling a module will get the local header and etc...where ever your make file points. Things to check here is 1. you want to try different compilers. 2. you want to try different kernel versions.

Use dmesg to get the error information and send it to me. Maybe I can help you. Thanks a lot!
