The 3c509 can't and you can't load the driver multiple times because of
the way 3c509 are detected (there is a static counter telling the driver
which adaptor to detect). I have fixed the 3c509 to support multiple
adaptor and the fix is now part of kernel 2.1. I am including the fix here
as it works correctly.
