Hi Alan,

Please apply the attached patch. Its an update on my previos patch with a
rewrite of the simplex code. The patch now does the following:

        # Make simplex detection on a per drive basis and dynamic for use
          with hotplug.
        # Make sure we also enforce simplex rules when using hdparm.
        # Make sure we also enforce simplex rules when using BIOS timings.
        # Moves BIOS timings IDE detection into chipset drivers (by providing a
          library function).
        # Provide the above library function that sets default values for tune
          parameters. It also handles the special case where user has requested
          to use BIOS IDE timings. Caller is assumed to support DMA
          on/off probe using the dma_status register unless a dma_check funtion
          is provided (note, the tekram driver is somewhat different from all
          the others, and haven't been updated yet).
        # Makes BIOS IDE timings work for both IDE0 and IDE1 at the same time.

I'm not sure whether you already applied my previous patch, so let me know if
you want this on top of that one.

Cheers,
Torben
