Have you checked that the card is really running full duplex and 100m? I ran 
into a similar problem once when dual booting a laptop with a Linksys 
10/100 card. Under Windows, it correctly autoconfigured as full duplex 
100m, but Debian saw it as half duplex and 10m for some reason. Under those 
conditions, my transfer speeds were about the same as what you are seeing.
