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....
