That worked. The sad thing is that I read somewhere (probably on this list) that *forcing* 100 would _increase_ performance because there wouldn't be any auto negotiating. I added it to my rc.conf, but later I decided that it didn't help any so I ran ifconfig fxp0 media autoselect, but failed to change my rc.conf back! Now I have learned that not only did it not improve performance, it seriously crippled it. Thanks for helping me track that down.
