In theory, maybe. But have you seen the corresponding code in the linux kernel when they try to probe a partially known component and at the same time go around all kinds of bugs and errors and differences in silicon revisions? All those magic numbers and timeouts and dependencies that no one really can explain? Configurations pages are a thing of the past, nowadays they should at best be used for confirmation and sanity checks. Device trees are the future and have already improved and simplified hardware management a lot (specially on ARM).
