This is a bug in the ide layer as CF pcmcia devices are marked as
removable but the devices (and the behaviour of ide-cs) does not fit the
Linux definition of such devices.

See this thread: http://lkml.org/lkml/2005/9/21/118

I'm hoping to work out a patch to change this in a manner acceptable to
everyone but haven't found time yet. I've not forgotten though.
