* Basic braille screen reader supportSamuel Thibault2008-04-30
| | | | | | | | | | | | | | | This adds a minimalistic braille screen reader support. This is meant to be used by blind people e.g. on boot failures or when / cannot be mounted etc and thus the userland screen readers can not work.

| | | | | | | | | | | | | | The only relevant sign of port being ready is its board->ready since now. Remove all other flags for this purpose which are set almost on the same place. Move ports inside the board to be sure that nobody will grab reference to the port without being sure that it exists.
