The region is allocated for the socket in the PCMCIA core.  The ide-cs
driver releases the region because the kernel IDE driver refuses to
talk to the device if the IO region is already allocated.  After the
IDE driver shuts down, we re-reserve the region so that the PCMCIA
core can free it when it shuts down the socket.

As for why this misbehaves on PPC, I'm not sure.  It would seem that
the core code is not reserving (and freeing) the region as expected.
