Did you enable this?
  echo -n 1 > /sys/devices/pci0000:00/0000:00:1e.0/0000:15:00.0/0.0/allow_func_id_match
You can watch "udevmonitor --kernel" while doing this, to get the path and
see what events the kernel creates.

Distros usually set it automatically by udev:
  ACTION=="add", SUBSYSTEM=="pcmcia", ENV{MODALIAS}=="?*",
ATTR{allow_func_id_match}="1"
