The parallel scanning feature is somewhat irrelevant on an original PIIX,
if the hardware even supports it which is somewhat of an unknown. If you
have a minor boot time performance concern you'd buy a real computer
instead.

And the other stuff you actually create a problem rather than solving one
- the difficulting testing the rare chips makes it harder to fix ata_piix
bugs and do full testing.
