insmod -f is intended for binary only modules which end user can't recompile
for his kernel.

make distclean
cp YOUR_CONFIG_HERE .config
make oldconfig
make dep && make clean
make bzImage && make modules
Always run "make distclean" before "make oldconfig". "make distclean"
removes .config file, so .config must be saved to some other file ("z") or
copied from elsewhere else.

Configuration of kernel that you are compiling is irrelevant to your running
kernel.

Above may work. I recommend full recompile without CTRL-c tricks.
