Ooh, true! What *is* the insertion order... the order they appear in
kallmodsyms? ok that's more or less entirely arbitrary: the only
ordering in there is "built-in before loadable" and that's just as
easily done via two-stage lookup if anyone cares (which nobody does: I
doubt there's any point preserving it).

It's easier to keep the property we actually care about via simply
looking for things in the dtrace and vmlinux modules by hand first.

ok, so, patch series v3 coming, hopefully today, dropping the modlist
too! :) bwahaha
