since some revisions of some chipsets must _never_ be placed into DMA
mode due to hardware bugs. Even if the user selects CONFIG_IDEDMA_AUTO.
The code in sl82c105.c knows about the chipset revisions that this is
required for, and it looks like the code in ide-pci.c will override the
chipset if CONFIG_IDEDMA_AUTO is enabled.
