Yes, you can lock to only load signed modules, and I think you can also
lock to no longer load any modules, i.e you can load a few modules at
boot time, and then ask the kernel to no longer load any other module.
I don't have a reference for that, but I'm pretty sure it was discussed
on LWN some $time ago.
