http://lkml.org/lkml/2009/7/13/286 is the ACPI implementation. I guess 
that it could be done entirely in libata if the bus structure is 
exported, but that does then limit it to ata - the code would need to be 
duplicated if anyone wants to bind scsi devices. I've no real 
preference, but this was the implementation suggested when I last posted 
this stuff back in 2005 or so.
