Well, it is a bugfix for PMAC_MEDIABAY=y && BLK_DEV_IDE=n && MAC_FLOPPY=y. :) > I'm tempted to actually remove all ifdef's ... if you have a media-bay, > then there are about 99% chances it contains an IDE device, with the > remaining percent being split with putting a floppy or a battery in.

I'm more worried about breaking automatic build checking (make randconfig) than a few extra bytes so if you remove all #ifdefs you'll have to either make BLK_DEV_IDE_PMAC select PMAC_MEDIABAY or make PMAC_MEDIABAY depend on BLK_DEV_IDE_PMAC (otherwise BLK_DEV_IDE=n && PMAC_MEDIABAY=y will fail since mediabay.c is referencing IDE code).
