3c509.o with kernel 2.0.27.

That gives me one interface on 230h. There is no trace of the one at 240h.

The second insmod fails with "Initialization of
some_other_significant_name failed". After that there is no way to get in
touch with the second 3com. Even if I unload the first driver, the second
one fails. I can still reload the first driver again. And if I reboot the
system and load the second card first, its the first card that disappears.
