The atapi driver will only enable dma on atapi devices if they claim to at
least support UDMA33/UDMA2. This behaviour was changed from 4.x (Søren tells
me) because too many old devices which report bogus capabilities failed with
the wdma modes. If your device works fine with wdma, you'll need to enable it
yourself (Gary's suggestion is a good way to do it).
