Any board that uses pci_cmd646_ide_init(), pci_piix[34]_ide_init(), or
vt82c686b_ide_init(). These create a qdev providing an IDE bus. The
non-qdevified IDE controllers use ide_init2_with_non_qdev_drives()
instead.
Funny: g3beige has two IDE controllers, first one isn't qdevified
(created with pmac_ide_init()), second one is (created with
pci_cmd646_ide_init()).
Feel free to ask for more help!
