Cardbus does not work anymore for me in the latest -current. A cardbus
card (3Com 3c575) does not work. However, a PCMCIA card (3Com 3C589D)
does work. The difference seems to be that there is a
cbb0: disabling socket
now. I always had "bad Vcc request" warnings, but the cardbus did work
fine anyway. This is a part of /var/log/messages:
