Well, I mainly specified the device node for the IDE controller, because it works in compatible mode and thus the IDE driver needs to know about the I/O ports. I guess the driver doesn't probe the BARs, if the controller is configured for compatible mode (and AFAIK a VIA IDE controller cannot be made work in fully native mode). Also the ppc_ide_md function hooks are considered obsolete. The interrupts for the IDE controller are another story. Judging from what some developers wrote on this mailing list, there doesn't seem to be a way to define legacy IDE interrupts (14 & 15) for a PCI device node. Therefore I'll reuse the IDE interrupt quirk for the Pegasos. Gerhard -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS.
