    Sorry for late mail but I fail to understand why this was done and
    what this patch fixes.

    libata has different mode programming code where first always the PIO
    mode and then DMA mode is set. With IDE core, the order can be
    different, PIO mode programming shouldn't affect DMA mode bits -- and
    does not affect it in the other drivers...
