No you should not. it is a big pain in the ass, and completely
unnecessary.

it can't do that. When pccard detaches, it detaches its children.
with nothing there to reattach the devices to pccard.

That's why pccard tries very hard to refuse to export ANY symbols that
pccard client drivers use. Other busses should do likewise.
