If it is a 3c905 card you should (or even have to) use a special driver
written by Donald Becker <becker@cesdis.gsfc.nasa.gov>. If i am not wrong
you find it something like http://cesdis.gsfc.nasa.gov in some subdirectory.
For me it works ok. If you don't find it let me know and i mail the driver
to you.
