No, you're wrong.  You can send the card a sequence of inputs that, if
it's really a Lance, will cause it to generate an interrupt.  If you
don't get an interrupt on the line you expect (or you get one on a
different line), you fail the probe.

You can then have multiple config entries at different IRQs, and
whichever one succeeds will be used, ignoring the rest.
