I don't have any of the ultra33 (20246) controllers... but I do have
CONFIG_PDC202XX_BURST set (ie. the "enabled special dma feature").
everything is more or less normal except that I think hdk in the box is
slowly dying at this point... this box has 8 drives on four controllers
rather than 12 on 3
