A quick "git grep -l ahci" says that in addition to q35, three ARM boards have an AHCI controller: highbank, cubieboard (also known as allwinner-a10) and xilinx-zynq-a9 (also known as xlnx-zynqmp). Everything else that has IDE really means parallel ATA.
In practice the only difference between the two is that parallel ATA distinguishes master/slave, while serial ATA has only one unit per bus (in addition, PATA has two buses while SATA/AHCI has six).

That's not exactly true since g3beige has a PCI controller. It may well be that IDE is the only one supported by the firmware. > So now I'm wondering how I can determine what other > machinetypes have an integrated IDE controller, so that I can add them > to this check.

It's actually called g3beige. :) Paolo
