*Don't* do that. The Linux IDE support is not hot-swap capable at
present. You will break things.
The fact that it works as well as it does is nice, but it's broken. You
need to properly clean-up the interface before you remove the card.
You should make sure that you use sync(1) to flush all the buffers to
the device, then use cardctl(8) to eject the PCMCIA slot that the card
is in.
That will cause the IDE resources to be cleanly deallocated without a
risk of fscking up your system. Then you can eject the card.
