Hi, I've got the feeling that those two parameters don't do the same 
things, although they have the same description ;-) Maybe the texts 
could be:
* The fixed amount of bus space which is reserved for the CardBus 
bridges IO window.
* The fixed amount of bus space which is reserved for the CardBus 
bridges memory window.

See you,
