OLDCARD from FreeBSD 4.x didn't have a match routine, since the
devices were matched and enabled via userland code (pccardd).
NEWCARD does have all the necessary infrastructure in the kernel
and doesn't depend on pccardd/pccardc any more. The downside is
that each device driver must know which devices it can handle.

There are currently two ways to achieve this. The first is adjusting
device_probe to correctly detect the presence of such a device. The
other way I'll work on the next few days is to add card_compat_match
routines and use the OLDCARD/NEWCARD compatibility layer.

In the long term it is preferable to have all devices support the
native NEWCARD interface and drop OLDCARD. That will need quite some
