Thinking ahead, by the 2.8 timescale, PATA could well be legacy hardware 
which could be supported only by an 'old' IDE driver, much like we already
have at the moment - I.E. we could remove the current 'old' IDE driver
sometime during the 2.7 timescale, and support SATA only via the SCSI layer.

This would save having any more than the minimum SATA code going in to the
existing IDE driver, and consolidate work in the future.        

The bloat of the SCSI layer in embedded machines might be a concern, but  
then again, maybe it won't - how many embedded machines are going to be   
using SATA, anyway?  Once we move away from spinning disks towards solid
state storage, (which is going to happen first in the embedded market),
will we want to use *ATA or SCSI at all?
