A. Use 'ethtool' or 'mii-tool' to force duplexing. (This is especially true 
if you start using the tg3 driver instead - it does not support kernel 
module options for duplex settings.)

B. Add the option 'auto_speed=0'. This is not intuitive and took me parsing 
the source of the module to find it :-)
