In DMA modes the 32bit I/O feature and multi-sector mode are not used. For
the moment libata also only supports 32bit PIO on some controllers and for those
it si handled automatically. Over time it may well gain 32bit support for more,
but again the goal is it will be entirely automatically done if so.
