This chunk of the pcidump output is an artefact of the dino(4) behaviour
and should be ignored.

So it looks like your board is not recgonized at all. Can you check that
it works in a different machine? Also, you might want to check the
respective voltages of your board and the PCI slot you're using - the
C360 has two 5V slots and two 3.3V slots.
