This problem should be fixed in the updated patch at the same URL. It's true that there are still some error handling problems in my patch. I actually should have said this is a first draft patch and I intended to clean it up :-). Can someone with an older card (those who *don't* print "detected 3c905B or higher") test the updated patch ? I don't have any of these cards so I can't test it myself.
