This is the first clue.

Hmmm, it appears that either
- your card is programmed to use only the 10baseT transceiver, or
- you are passing an invalid transceiver-setting option

That will show us the EEPROM setting.

Yup, the transceiver type for this board is "NWay". Any other setting
will put the board into 10baseT, non-autonegotiate mode.
[[ Quick poll: I've been considering changing the configuration EEPROM
report. The current semantics are
-e Show the interpreted settings
-ee Also show the whole EEPROM contents numerically
-eee For EEPROM values that look like ASCII, print the characters at the
end of each numeric output line.
Should all three types of output be shown with a single "-e"?

This really sounds as if you have an option in /etc/modules.conf.
The driver is designed to work with _no_ options.
The only reason to pass an option is to work around a specific flaw in
your environment or configuration.
