 Hmm, probably we should ask a person who implemented it,
 but my assumption is that it was just a hack since
 we didn't have proper hooks to defer initialization
 after mountroot(9).

 IMO we should have firmware in root file system as kernel modules
 and we don't have to defer it to an rc script.
 Anyway, your suggestion looks beyond the scope of this PR.
