There's a libata > driver for it nowadays, so you can use PATA_MACIO instead of IDE_PMAC Thanks for that, Ben: I remember you were brewing up such a driver, but I missed when it actually went in. I can confirm that switching off CONFIG_IDE and switching on CONFIG_PATA_MACIO and CONFIG_BLK_DEV_SR now gives me a booting system with a working CD-ROM (though I've not yet tried burning). Whereas CONFIG_IDE=3Dy with current git still does not boot: hangs for a minute or three around the windfarm announcements, then an endless splurge of hda error messages - sorry, I'm not being helpful, other worries...
