: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?
:...
:NATA doesn't attach as AHCI because this chipset doesn't support AHCI (and 
:NATA can somehow check for that).
    No, but this is my fault because I have those chips listed in the
    ahci_attach.c code as being AHCI capable.
    Could you do a bit of research and tell me which of these are NOT
    actually AHCI-capable ?  I'll then remove them from the AHCI driver.
