The only thing special that I believe you have to do is provide an
additional DRIVER_MODULE line to attach to cardbus in addition to (or
instead of) pci... For example:
DRIVER_MODULE(re, pci, re_driver, re_devclass, 0, 0);
DRIVER_MODULE(re, cardbus, re_driver, re_devclass, 0, 0);
Warner is the expert on cardbus, so, if you have any questions, you
could drop him an email....
Good luck!
