Use the Multimac MMLEM.OS2 driver. The IBM drivers never 
worked. E1000B.OS2 is the OLD Multimac driver. It will sometimes 
work, but not very well. PCNet-FAST III is a 100 Mbit driver.

I am not sure what you are actually seeing with more than one core. 
That should not make any difference to network activity, but it can 
cause hangs, and other weird things.
