Having written an SiI3124 driver for NetBSD (which won't be open-sourced as
far as I know) in my previous job, I can tell you that the SiI3124 interface
and the AHCI interface are different.

The good news is, that the NetBSD ATA code has been changed to not have
any dependencies on IDE registers in the controller-independent layer,
so new host interfaces like AHCI can be fit into the ATA framework
without having to change it.
