  Does that mean that the card isn't responding properly to what the driver
is telling it, but there still might be some hope of figuring out a way to
make the card stay full duplex when ifconfig requests full duplex?

  Is there a straightforward way to patch the driver to not change the
autonegotiated settings (recall that the full-duplex light on the switch
is on until ifconfig runs)?
