The handling of this stuff was a little confused in the 2.2.16
driver - the user's attempt to override things on the insmod
command line tended to get overridden by the driver!

I suspect that if you take the 2.2.19 driver all will be sweet.

However, if your NIC's EEPROM is correctly set up then none
of this is necessary.  I bet you EEPROM isn't selecting
autonegotiation.  If you can, grab 3com's DOS-based setup
tool from ftp://ftp.3com.com/pub/nic/3c90x/3c90xx2.exe and
check those EEPROM settings.

Please let us know the outcome.  Thanks.
