Well, it's the right thing to do (libata does it) but presumably doing that in old IDE is triggering some kind of bug. Unless there's a specific problem it was solving, or someone is interested in debugging in detail (I'm certainly not interested in drivers/ide) it should likely be reverted as we've done without it for so long..
