    No, the count of tulip is 1. This is strange. The driver does not show
anything, and the card service shows
the following message cs: cb_free(bus 2)
Now, I test the driver.

1.insmod pci-scan.o
2.insmod tulip.o
3.remove the cardbus.

The same situlation happens. I type the command "ifconfig -a" eth0 exists
when I remove the card.
