As someone pointed out, I did not explain this step clearly enough.
Our standard defconfig has many drivers enabled as modules. To make
things easy during development however, we usually build monolithic
kernels. It saves you from having to copy all the drivers along with
the kernel.

So I run a quick search and replace over the defconfig file, changing
every location where a driver is set to module ("=m") to be a built-in
driver ("=y"). There's a few ways to skin this cat, my quick one is

  perl -pi -e 's/=m/=y/' .config

cheers,
