Kinda like the "ide0=serialize" flag for the IDE subsystem, I suppose.
We certainly don't want it to be the default, as millions of ata_piix
systems already out there seem to be working just fine (not all of them

identical models).
It must be something new with ICH8 that we're not doing correctly yet.
