A kernel module could be easily compiled out of the kernel. You should 
have a Makefile included with your driver. This Makefile will use the 
kernel Makefile to build, so you have to be sure that KDIR is pointing 
on the root directory of your kernel. If build with buildroot it should 
be something like buildroot/output/build/linux-x.y/

I will probably also need to set INSTALL_MOD_PATH to point on your rootfs.

But as suggested before if the driver is GPL you could add it directly 
in your kernel tree it would be cleaner.
