also, for hard data, an Alpha4000 w/ 512MB RAM does a bit over 80Mbps on 100bT just shoving data from /dev/zero. from my knowledge of crusoe, i gather it's patethic as a bit mover when compared with an axp system.
on pratical reasons, why do you need 1Gbps on such a small device ? it's not like you can actually generate data that fast :) a 100bT *good* chipset (dirt cheap compared to gigE) and a reasonable amount of mem (>32M) would probably be faster and render better results
cheers
