New CardBus _controllers_ are really much alike PCI devices. You can plug your 16-bit card there and share interrupts. The document you quote is a bit outdated, if you are interested in past discussions about it please see Warner's excellent presentation at http://www.usenix.org/events/bsdcon02/full_papers/losh/losh_html/index.html Please also understand that with new 32-bit controllers (cbb drivers and others) old tools like pccardd and pccardc do not work and are no longer necessary. They access old 16-bit interface only. Regards, --Marcin
