A summer intern of mine just experienced the exact same problem with a
3c509. He cured it by stripping the driver for the second
(nonexistant) floppy out of the kernel and rebuilding. (Well, by the
time I got there, he'd stripped other things out, too.) I cannot
explain why this happens, as I didn't try debugging the kernel.

I'd suggest that someone file a send-pr on this.
