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.
