Do you mean ide_release in ide-cs.c, or ide_unregister in ide.c?

Well, the problem is that there is no way to say that there is a hwif present without any drives. The low-level driver (i.e. pmac.c) has to leave hwif->present = 0, because if you set hwif->present = 1 then the ide probe code won't go looking for drives. The probe code then only sets hwif->present = 1 if it finds a drive. If hwif->present gets left at 0 then it is liable to be taken over for a pcmcia card.
What would be good is a way to say "I know this hwif is definitely present, please probe for devices attached to it, but don't decide it's not present if you don't find any devices". I would like pmac.c to be able to set hwif->present = 1 but still have the probe code go looking for devices.
