In the case of CF cards in ide-cs, removing the card is equivalent
to removing the entire IDE controller, not just the media.

It isn't the same as removing the entire PCMCIA controller layer. As far
as PCMCIA is concerned there has been no change. Thus we have no media
change event and we need ->removable = 1

CF slots have card detection and ide-cs will see a card removal event.
Have a look at ide_event() in ide-cs.c: CS_EVENT_CARD_INSERTION and
CS_EVENT_CARD_REMOVAL are what they say...

If the PCMCIA card disappeared each time it would be different

Just the card disappears.

This along with your comments about the IDE layer having no hotplug
support suggest the code in question can be removed pending a better
replacement when hotplug is implemented.
