Agreed.

This goes back to what I was saying about sleep.mod not being sensibly
able to depend on normal.mod, so in order to do this kind of this we
either need shared code in the kernel (best avoided) or a new module
common to both.
(Or we could do something like exporting grub_dl_resolve_symbol so that
we have dlsym-like functionality. But this is starting to look rather
baroque just for the sake of avoiding a transient environment variable,
IMO.)
