insmod NAME.o only looks in ./ !

simply put them in the system wide modules location in 
/lib/modules/KERNEL_VERSION/misc/ and run depmod -a as
root. Most setups also allow to use the default location
/lib/modules/misc for such modules - but then its naturally
up to you to make shure that the kernel version is corect.

basically insmod checks the /lib/modules/`uname -r`/modules.dep to find
where the module is located, that is if you do insmod MODULE_NAME without
the .o extension - if you use the .o extension then it will accept the 
absolute path or take ./ by default.
