You shoudn't have to.  A driver reload is supposed to restore the card
to operational state, even if the previous configuration was bogus.

Yes.  That's an excellent approach!
It's possible that the changed register is in the MII management
section, so dump those registers as well (the -m option to the diag
program).

Very useful info!  We do have reports of the card working.  This
confirms that there are multiple version of the card

The driver uses the table entry:
	{"3c1556B mini-PCI",{ 0x605610B7, 0xf0ffffff },
which matches IDs 0x6*56 (0x6056 0x6156 .. 0x6f56).
What are the IDs of the two cards?
