If your module is replacing a driver already in the kernel tree then it 
should go in /lib/modules/$(uname -r)/updates/

If it's a new driver not present in the kernel then it should go in 
/lib/modules/$(uname -r)/extra/

and then run 'depmod -a'

BTW, you should use modprobe and modprobe -r to load and unload modules 
rather than insmod as modprobe understands module dependencies whereas 
insmod doesn't.
