But Linus is wanting exactly that! As far as I understand, Linus would like 
a generic interface sitting at the higher layers, and that is used by the 
ide/atapi/scsi layers. I read this as implying that the user space 
interface will also be only one. It will talk to the higher layers, the 
lower layers can then do all the hw specific magic.

Just my 2p.
