Shouldn't this bug rather be filed against the kernel. The pata_macio
module doesn't autoload because the pci id of the keylargo controller
isn't listed in the pci match table of the module. The generic macio
code matches anything Apple (no idea why, too painful to find out all
ids?) and maybe pata_macio should, too.

ide_pmac and pata_macio have exactly the same table of PCI device IDs.

Probably irrelevant as ide_pmac was =Y intead of =M, no?

Further, if a device's ID isn't in the table then not only will the
module not be auto-loaded but loading it manually will have no effect
because the driver won't be matched to that device.

Some chips attach through pci, some through the macio platform driver. I think listing the pci id of the macio chip would allow the autodetection to work, but would probably not be the correct solution. Maybe the problem is in udev or whatever, I don't know anything about those things, or most other things for that matter, but I still don't think force-loading the module in initramfs is the cleanest solution. I'm also pretty sure that if the config had PATA_MACIO=Y, it would work.
