A similar approach like for the BT946C can be taken. I just did not have the time to add stubs for them, and to check whether the drivers are already flexible enough. (If nobody else beats me on this, I promise to do it before the end of the month ...) BTW: The I/O address is assigned by the PCI BIOS, and it does not suffice to set it to the port it happened to be at in some particular system. Moving it to another slot may change the I/O address, for example ...
