You could try setting the internal NIC to half-duplex, or perhaps use a (passive) 10BASE-T hub instead of a switch if you cannot configure that internally, on the kernel command line, or doing it in userland is too late.
I actually had the port configured to half-duplex at first. But I was distracted by the high number of collisions taking place and so changed it to full-duplex.
