[ros-diffs] [ion] 24439: - More re-shuffling of initialization calls, including enabling access to the blue screen much much earlier (no point in doing it so late, but this change is not that useful since soon we'll have bootvid). - Split Po init in two, so the early Po init (which we'll need to do eventually) doesn't depent on the later Po init (which uses a PnP notification which depends on the Io system). - Make I/O initialize quite a bit later.

Log:
- More re-shuffling of initialization calls, including enabling access to the blue screen much much earlier (no point in doing it so late, but this change is not that useful since soon we'll have bootvid).
- Split Po init in two, so the early Po init (which we'll need to do eventually) doesn't depent on the later Po init (which uses a PnP notification which depends on the Io system).
- Make I/O initialize quite a bit later.
