My cheap rl card performs better with auto than with either 100TX-full or 100TX-half ('tho its always auto'ed to 100TX full duplex anyway). And by way of interest, I have just experienced a similar problem with NICs + 100 baseT switch - it was a 3Com Office connect card (xl driver) that I had the issues with, and ended up replacing it with a DLink (vr driver).
