On my system with ICH7 I have to use this, otherwise my SATA ports won't
show up - AHCI tries probing and fails (some memory range reservation
error), but NATA never takes over. We certainly should avoid these
situations. Is there a way to pass attachment to NATA if AHCI can't
figure it out?
Relevant pciconf output:

NATA doesn't attach as AHCI because this chipset doesn't support AHCI (and
NATA can somehow check for that).
