I need two years for solve this behavior... but It's VERY easy:

ALL actual linux's drivers for 3Com & Intel (3c95x and eepro100)
have this bug. This two NICs have a BIOS with boot parameters. The
problem is if your NIC are configured for forced operation in the BIOS;
in this case the driver don't select the proper transceiver. Test to change
your boot config to "AUTOMATIC" in Link Speed AND Duplex Mode.
For my cards this is all that I need to run properly with Autoselect NWAY
in Linux.
