Documentation/ide.txt (from the Linux kernel tree) shows the ide options
available at boot, and includes this line:

 "idex=dma"             : automatically configure/use DMA if possible.

I don't see any mention of ata or udma options there, but you could try
and see if "ide0=dma" does anything for you.
