Yes.  I hope that it would make things a lot faster, especially over the

showing a menu and booting from there; now when we have hierarchical menus.

Hm.  We could rather easily deal with that by storing the full path of
the module; that way we can distinguish them.

closely coupled with the bootstrap part of the bootloader itself.
