You should just be able to copy the .ko file as you said, and 'insmod' will
work.  For 'modprobe' to work correctly, running
 depmod -a
after the copy is usually a good idea.

There are some more steps if you need that module to be available before the
root filesystem is mounted (ie it's a driver that you need in order to
access your root filesystem) via an initrd image, but I'm guessing you're
not trying to put your root filesystem on tape, so that should be enough.
