Well - most likely the (very recent) IOS wants to display something, but
has no driver support to ask the (very old) hardware...

That's too much.  If there is no other traffic on the wire that might
cause multiple collisions and packet drops, you should not see more than 1
packet lost (the first, if any).

My 4700 with NP-6E does also print "Unknown duplex", but pings perfectly
clean:

Sending 1000, 100-byte ICMP Echos to 195.30.0.126, timeout is 2 seconds:
Success rate is 100 percent (1000/1000), round-trip min/avg/max = 1/6/332 ms

(there is some other stuff going on in this network, so the high max RTT
is not something I seriously worry about)
