Well, what I meant for external built modules are not about things like nvidia, but rather normal (legal) drivers or updated modules that are built from out-of-kernel source. I'm sure that distros will provide such update module packages on the secure boot system, too. So, discussing about "how" isn't so bad even for now, since this shall be anyway mandatory (for distros) once when the module signing is deployed.
