Hmm... have you checked to make sure you have the appropriate
chipset-specific IDE DMA support enabled?  This can make a difference.

I generally set CONFIG_IDEDMA_PCI_AUTO to make sure that the DMA
settings are automatically set to the correct values.  (I'm not an
expert on hdparm to set DMA/Ultra-DMA settings, but I'm not convinced
-d1 is sufficiently to completely set up the DMA settings correctly.)
So I prefer to let the kernel set everythign up for my correctly.
