Looks like my problem is just old firmware that does not have the
EEPROM reference tables needed by the WLE900VX.

But, if I hack on the OTP logic and make it use a reference table
for the reference design the NIC claims (XB140), then the NIC does
show up as 3x3, and gets proper MAC, etc.

This is a nasty hack, but maybe it will hold me over until I
can get access to a more proper solution.
