[SqNOS] We can now send ethernet packets!

[Johnathon Meichtry]

Gera,

Fantastic and well done.  Your right, this is very very exciting!!!  I can't 
wait to get it the latest installed and give it a go, if only SqueakSource 
wasn't down right now  :-( but fingers' crossed it'll be working again later 
today.

Regards,

Johnathon
