My guess as well, the link detection might be broken. netcfg should really have an option to force enabling the interface even if link detection fails.
However, when no link is detected, some ethernet drivers disable TX completely. When it was first introduced for my old dmfe card, it was broken and I could receive packets, but nothing was ever transmitted - after my bug report they reverted the changes and reintroduced a working link detection in the next version. My point is, even if you fix netcfg, Eric's driver might be just as broken so he still has to reconnect the cable to make it work.
Might be nothing, but you could play with the module parameter mentioned here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=...
