This is somewhat intentional; if you update your kernel source and
recompile the kernel without recompiling the module, there's a good
chance your kernel will panic when you try and use it.  If you're not
planning to update your kernel sources but just want to recompile the
kernel with different options, there are other directories that are
checked for module loading - see the loader.conf manpage.
