you need to find out which chipset they are using to talk to the ide buss

	- if the kernel you're using doesnt support the ide chipset
	( southbridge?) than it will give you "operation not permitted"
	error message for "hdparm -d 1"

and all other prior comments about what to do to fix the "enabling dma"
problems .. ( esp which kernel and which chipset )

and yeah.. dell likes to make their own proprietory variations too
