OK, I'm almost out of ideas about how to turn on this transceiver.
The final idea is  that this isn't a regular Tornado chip with
on-chip transceiver.  One of the CardBus cards requires this:
    (FEATURE_TORNADO & ~HAS_NWAY)
ending up with
   (FEATURE_TORNADO & ~HAS_NWAY)|HAS_CB_FNS|EEPROM_8BIT | MII_XCVR_PWR, },

That register has been renamed to MediaOptions in the 3Com docs.  The
driver uses the name Wn3_Options.  Most bits are read-only with the
initial value coming from the configuartion EEPROM.
