Well, I don't know if answering my own question is a good thing or
not, but here goes.
After some assistance from Javir Martin Rueda <jmrueda@diatel.upm.es>
the author of the ex driver, I figured out that Intel is now shipping
EtherExpress Pro/10+ cards with a different prefix on the MAC
address. The prefix of the MAC address is used to determine if the
card is a Pro/10 or a Pro/10+. Adding my prefix to the code fixed all
my problems.
Here are the diffs against the 3.0-RELEASE if_ex.c driver:
